Help With Chemistry Baking Soda And Vinegar Lab ;

Baking soda and vinegar chemistry lab help?

It says I need to calculate the theoretical yield in grams of CO2 from the initial amount of limiting reactant.

Now the limiting reactant was the baking soda.
We started off with 2 grams of baking soda.

So how do I answer the problem? Steps would be nice.


I also need to know how to calculate the percent yield of CO2 for my reaction.

I know how to do percent yield I just don't know what numbers to use? Like which number is the actual and which is the theoretical?

Other than these two questions the rest of my lab is done so I have all the numbers.

Vinegar and Baking soda?

The law of conservation of matter states that matter is neither created nor destroyed, it only changes forms. When you combine vinegar and baking soda a chemical reaction occurs. This is evident by the bubbling and the release of gas. An easy way to see this is to take a balloon, small empty plastic bottle (water bottle), baking soda, and vinegar. Put the baking soda in the balloon and the vinegar in the bottle. Now with the balloon hanging down, put the end of the balloon over the top of the bottle. Place the whole thing on a scale and record the mass. Pull the balloon upright tipping the baking soda into the bottle. A reaction should occur and the balloon should blow up. The mass should not change. This proves the law of conservation of matter and that gas does have mass.

However if you were to take the balloon off of the bottle the mass would drop because of the mass of the gas.

Make sure that you do not use too much chemicals as the balloon would explode and you can't prove that the mass stays the same.

What happens when you mix baking soda and vinegar?

Mixing vinegar and baking soda produces a very exciting chemical reaction- it’s often one of the first science experiments that children do in school, and it’s very fun to watch!Vinegar is a diluted form of acetic acid and baking soda (or sodium bicarbonate) is a base. When you mix the two together, the solution begins to become bubbly and frothy. What happens is that carbonic acid and sodium acetate are produced, which then begin to decompose and form carbon dioxide gas and water, causing foamy bubbles, as the CO2 is heavier than the air around it. The equation can be written like this:NaHCO3 + HC2H3O2→ NaC2H3O2 + H2O + CO2What results from the reaction is a diluted acetic acid solution, and in baking, this works as a leavening agent to help your baked goods rise (you put this in the baking category, which is why I brought up the baking aspect). If you want to become a great baker, it’s imperative that you learn the more scientific side of baking- with better understanding of the chemistry of baking comes better results in your food!

HELP!!!!! WITH CHEMISTRY BAKING SODA AND VINEGAR LAB ; ( ?

The lab wants me to find the volume of a 1-quart bag, then determine the mass of bakaing soda (sodium hydrogen carbonate) that will fill the bag with CO2 gas when the compound reacts with excess acetic acid (vinegar). I need to know how much of baking soda and vinegar to put in the bag?? it says to use stoichiometetry and conversions can someone plzzzzzz help?!!! really confused ; (
IT SAYS : 1) solve for moles of baking soda needed
2) amount of baking soda needed in GRAMS
3)moles for vinegar needed
4) amount of vinegar needed in mL (vinegar has 0.80M)

Chemical Reaction between Baking Soda and Vinegar?

simple: If you want the answer with no blabber then look at the bottom equation...

Baking soda, a pure chemical called sodium bicarbonate, has the chemical formula:

NaHCO3

When dissolved in water baking soda separates into sodium (Na+) and bicarbonate ions (HCO3- ):

NaHCO3 ---> Na+(aq) + HCO3-(aq)


Vinegar, a weak (5%) solution of acetic acid in water, partially dissociates into hydrogen ( H+) and acetate ions (CH3COO-):

CH3COOH <--> H+(aq) + CH3COO-(aq)

The reaction between baking soda and vinegar is actually two reactions, an acid base reaction followed by a decomposition reaction.

When the two ingredients are mixed, hydrogen ions ( H+) from the vinegar react with the bicarbonate ions (HCO3- ) from the baking soda to form a new chemical called carbonic acid (H2CO3).

H+ + HCO3- ---> H2CO3

The carbonic acid thus formed then immediately decomposes into carbon dioxide gas (CO2)and water (H2O).

H2CO3 ---> H2O + CO2

It's this carbon dioxide gas that you see bubbling and foaming as soon as you mix baking soda and vinegar together.

Using the molecular structures of only the components involved, the chemical reaction can be written:

baking soda and vinegar reaction

The overall reaction however, is often written as follows:

NaHCO3 (aq) + CH3COOH (aq) ----> CO2 (g) + H2O (l) + CH3COONa (aq)

Your welcome!

What's the purpose of baking soda+vinegar experiment(chemical eruption)? [chemistry,investigatory project]?

It is a very visible experiment that shows very clearly the results of reacting a acid to a base. This reaction generally makes a salt. There are lots of acid base reactions that you can't visibly see the reaction taking place. In acid base reactions, the acid (vinegar) donates a hydrogen proton to a base (baking soda) which accepts the proton with great fervor

But with soda and vinegar you get an ebullition of CO2 bubbles which bubble up and get coated in the baking soda paste and so form almost soap like bubbles and don't break up very easily.

So again, it is just an easy and safe acid base reaction that clearly gives a gratifying experience of seeing a reaction taking place. If you taste the baking soda residue afterwards you will also see that is has a much saltier taste than before the reaction.

Why is baking soda and vinegar considered a chemical reaction?

Because, quite frankly, it is a chemical reaction. You have new substances being formed from the two substances in addition to one of those new substances being a different state of matter from the others (gas as opposed to solid or liquid).

Which is best for removing rust stains from clothes and why? Vinegar, baking soda, or toothpaste?

Which is best for removing rust stains from clothes and why? Vinegar, baking soda, or toothpaste?None of the above is hugely successful in removing rust stains. Those frustrations are particularly pesky to get out of clothing if there is any age on the stain. Like all surprises where they shouldn’t be, stains need to yanked as soon or as fresh as possible.I had a grandmother that swore by salt and lemon juice. Followed by the bleaching summer sun. Do not underestimate sunlight and don’t overlook this part of the process. Sprinkle salt on the stain and squeeze lemon juice over the salt (bottled juice works as well). Scrub gently with an old toothbrush. Don’t rinse. Lay in the mid-day sun until the paste is dry. Rinse out the dried crust. If a hint of the stain still lurks, repeat the same process again. Yep, these are pesky buggers to remove, success increasing on how fresh is the discovered stain. If time is an unknown, hope of a pristine recovery plummets.If the fabric is colored, test the lemon juice in an inconspicuous spot as the citric acid of the lemon can pull dye out. Removing rust stains is the most successful on white or cream fabrics. Rust cannot be removed in regular laundry and, whatever you do, never run through a hot dryer or iron a stained fabric as high heat will set the stain. Bleach is a big NO with rust, setting the stain permanently instead of unseating it.I imagine that vinegar might perform close to the lemon juice, with baking soda perhaps acting as an abrasive but I cannot add much experience to that statement as I abandoned alternatives after trying salt and lemon juice. Toothpaste I save for impromptu cleanings of silver jewelry.

Chemistry lab?

The chemical reaction between baking soda and vinegar is multi stepped.

Vinegar is acetic acid: CH3COOH
Baking soda is sodium bicarbonate: NaHCO3
Mixing the two is simply and acid base reaction.
CH3COOH + NaHCO3 ---> CH3COONa + H2CO3
That last product is carbonic acid which quickly decomposes into
carbon dioxide and water:
H2CO3 ---> H2O + CO2
The CO2 is what you see foaming and bubbling in this reaction.

Since I don't know the size of your ziploc bag, nor do I know the molarity of your acetic acid(vinegar), I found a website for you that illustrates and lists the amount of baking soda and vinegar you need to inflate a balloon.

Good luck on your lab

How many moles of baking soda will react with 1 mL of vinegar/?

CH3COOH + NaHCO3 >> CH3COONa + H2O + CO2
