Salt Is The Product Formed By A Reaction In Which ____ Atoms Of An Acid Are Replaced By The Atoms

What is the chemical reaction of diluted phosphoric acid and sodium hydroxide solution?

Reactants:H3PO4(aq) + NaOH(aq).This is a double replacement reaction, and so the cations will switch from one compound to the other to form the products.Non-balanced equation:H3PO4(aq) + NaOH(aq) → H2O(l) + Na3PO4(aq).(H2O is formed by the combination of H (from the phosphoric acid) and hydroxide).Now, the next step is to balance the equation. Phosphorus and oxygen are both balanced (1 P atom on each side, 5 O atoms on each side).However, there is 1 sodium atom on the left, but 3 sodium atoms on the right. To balance, add a coefficient of 3 before NaOH(aq):H3PO4(aq) + 3NaOH(aq) → H2O(l) + Na3PO4(aq).Although we have just unbalanced oxygen, we can make that up by adding a coefficient of 3 on H2O(l) to get the number of hydrogen atoms on the right equal to 6, the number of hydrogen atoms on the left:H3PO4(aq) + 3NaOH(aq) → 3H2O(l) + Na3PO4(aq).Let’s check to see if it’s balanced!• Hydrogen atoms on the left: 3 + 3 = 6. On the right: 3 * 2 = 6. Balanced.• Phosphorus atoms on the left: 1. On the right: 1. Balanced.• Sodium atoms on the left: 3. On the right: 3. Balanced.• Oxygen atoms on the left: 4 + 3 = 7. On the right: 3 + 4 = 7. Balanced.And we’re all done! Thus, the balanced chemical equation for this reaction is:H3PO4(aq) + 3NaOH(aq) → 3H2O(l) + Na3PO4(aq).I hope that helps! :)

How do I identify the compounds in the following reactions?

Reaction (A) - First check the products. Here, we are getting an alcohol and an acid. Hence, first one is esterification reaction. Compound A - CH3CH2COOCH3Reaction (B) - This reaction is also knows as hydrogenation of an alkene. Raney’s Nickel (H2/Ni) is used as reagent. In this reaction, carbon-carbon double bond breaks up and hydrogen atoms are added to balance the valency(4) of each carbon atom. Compund B - R2CH-CHR2Reaction (C) - Here you can see, reaction is taking place under sunlight. Hence, this reaction is known as Halogenation reaction. In this reaction, 1 hydrogen carbon atom is replaced by a halogen (in the question chlorine is given).Compound C - C2H6Reaction (D) - This one is factual and it must be remembered. When an acid reacts with sodium bicarbonate( Na2CO3 ), hydrogen gas (H2) is released. Also, salt of an acid is also formed ( as you can see in the reaction ). CO2 is also released. Compund D - CO2Reaction (E) - CO2 reacts with Ca(OH)2, CaCO3 will be formed. (Factual)Reaction (F) - Maybe it’s a combustion reaction. Hence, compound F must be O2.

Why does phosphoric acid form three series of salt?

The formula of phosphoric acid is H3PO4.It can give 3 hydrogen http://atoms.it reacts with a metal atom to form a salt.H3PO4 +Na —→ NaH2PO4NaH2PO4 + Na —→ Na2HPO43. Na2HPO4 + Na —→ Na3PO4NaH2PO4 and Na2HPO4 are acidic salts. Because even though they are salts they can they can donate H.Na2HPO4,NaH2PO4 and Na3PO4 are the three forms of salts of H3PO4.I know this.If anything wrong please forgive me

Is salt an acid?

I’m assuming that by ‘salt’, the OP’s referring to ‘table salt’.Salt is a salt. First of all, an acid (Bronsted-Lowry, not Lewis), by definition, is ‘a donor of protons’. Do you see any hydrogen ions (hydrons, basically protons) in a lattice of table salt? Even in terms of Lewis acids and bases, sodium atoms and chlorine atoms, being extremely reactive, are quite satisfied in ionic form and thus will not accept more electrons.Now to explain what a salt is:One by-product of a base reacting with an acid is a salt. The other is water.Or if a metal reacts with an acid, the products are a salt and some hydrogen.Either something like this:NaOH(s)+HCl(aq)->NaCl(aq)+H2O(l) (I know, table salt technically dissociates into ions, though.)Or like this, results in formation of salts: 2 Na(s)+2 HCl(aq)->2 NaCl(aq)+ H2(g) (Pure sodium is possible only when you separate it from a compound and store it in a noble gas/oil.)hEy gO bAcK tO cHeM ClAsS iF yOu AsK $#!+ lIkE tHiS aGaIn EvEn A %()cK!nG 14 yEaR oLd KnOwS tHiSSorry for being a blunt arse. I guess acidic salts are possible, but highly unlikely: when the acid has more hydrons that the number of hydroxide ions the base has or creates in water. Take sodium bisulfate for example.Equation here: H2SO4 + NaOH → NaHSO4 + H2O (possible under exact ratios, otherwise sodium sulfate would have been produced.

What is sodium salt and how would you calculate its formula?

A sodium salt is the product of a reaction between an acid and a sodium base(alkali) with hydrogen ion of the acid being replaced by the sodium ion.An example of this is sodium chloride, or table salt. The chemical reaction is :HCl (aq) + NaOH (aq) -> NaCl(aq) + H2O(l)Where the H+ ion in the hydrochloric acid is replaced by the Na+ ion from sodium hydroxide.To calculate the empirical formula, simply find the percentage by mass of each element in the sodium salt compound, divide this number by the respective mass number of each element. Then, divide all of the resulting numbers of each element by the smallest number, to find the ratio of number of atoms of each element in this compound. Round of each number to the nearest whole number. You will have the empirical formula of the compound. Usually, in chemistry questions, the relative molecular mass of the compound is given. To find the actual chemical formula, add up each element present in the compound using its mass number. For example, if salt is sodium perchlorate has a chemical formula NaClO4. The relative molecular mass is thus 122.5. Divide the mass the question by the RMM of the empirical formula. This will give you the no. of times which the actual chemical formula is larger than the empirical formula. Multiply each element in the empirical formula by this number, and you will be able to find the actual chemical formula of this compound.

Is neutralisation of calcium hydroxide with hydrochloric acid an example of physical or chemical?

Is neutralization….physical or chemical? Well, this is a difficult if not impossible question to answer because chemistry is the study of matter. But wait, isn’t studying matter what physics is all about? Yep, it sure is.The short answer to your question….the neutralization process is BOTH chemical and physical.So, what’s the difference between the studies of physics and chemistry? IN GENERAL (there is overlap) - physics studies how matter moves in space and time, and when it moves or interacts, how energy is affected. Chemists study how components of matter interact and the energetics of this interaction - but the interactions of these components is affected by how they move in space and time. Physicists often test their ideas using interactions of atoms - chemists do experiments with molecules that test the ideas derived from physicists studying atoms.Chemistry can be considered a subset of Physics, focusing on how atoms interact, how bonds form. But all these things studied in chemistry rely on understanding the laws of physics to fully explain. So, really, neutralization, being a chemical phenomenon, is both physical and chemical.Although you did not ask how adding HCl “neutralises” a basic solution of Ca(OH)2 let’s just over simplify the process to illustrate why we cannot assign this process to one or the other discipline.The neutralization of Ca(OH)2 (a strong base that in water dissociates to Ca^+2 + 2OH^-1) with HCl (a strong acid that in water also dissociated but forms H^+1 + OH^-1) occurs because the abundance of OH^-1 in a Ca(OH)2 containing solution is balanced by adding an equal number of H^+1 with the addition of HCl.For example, dissolving 0.5 moles Ca(OH)2 in 1 liter of water will result in a solution having 1M OH^-1 (for every 0.5 moles Ca(OH)2 that dissociates in solution, 2 x 0.5 mole = 1 mole of OH^-1 is released). To balance the 1M OH^-1 in solution, we would have to add 1 mole of HCl. A neutral solution is generally considered to be one having equal concentrations of OH- and H+ at equilibrium.The dissociation of these molecules in water (involving the breaking of ionic bonds between the added calcium hydroxide or hydrochloric acid) is a physical activity that releases heat. The interactions of the resulting ions with the polar water molecules in solution, also based on +/- charge interacions is also physical.
