Borax and HCl are in 1:2 molar ratio
What is the chemical equation of the reaction with copper oxide and hydrochloric acid?
Balanced:CuO + 2HCl = CuCl2 + H2OCopper Oxide + Hydrochloric Acid = Copper Chloride + WaterThis is a neutralisation reaction.
Help, water chem equations?
*** 1 *** temporary hardness is from calcium and bicarbonate ions in solution... Ca(HCO3)2 (aq) <----> CaCO3(s) + H2O + CO2. is the equilibrium reaction. When you heat the system, CO2 becomes less soluble in the hot water and evolves as a gas. This forces the reaction to shift right and form more CaCO3(s). when you cool the water, it is then "softer" *** 2 *** permanent hardness is CaCl2 and MgCl2 borax is Na2B4O7 soap is say.. sodium stearate... C17H35COONa in hard water... 2C17H35COONa + Ca(+2) ---> (C17H35COO)2Ca + 2Na(+1) where the (C17H35COO)2Ca is insoluble and precipitates out as a scum when you add borax, you precipitate out the Ca(+2) and the Mg(+2) CaCl2 (aq) + Na2B4O7 (aq) ----> CaB4O7(s) + 2 NaCl (aq) MgCl2 (aq) + Na2B4O7 (aq) ----> MgB4O7(s) + 2 NaCl (aq) leaving the sodium stearate free to dissolve in water.
How do I write a chemical equation of phenolphthalein and sodium hydroxide?
Phenolphthalein is a indicator used for determining the quantity of base. The structure of phenolphthalein is as belowWhen phenolphthalein is reacted with acid or neutral solution or water there is no reaction as phenol present in the structure is acidic in nature i.e. it has tendency to release H+ ions in the solution. In presence of acid or neutral solution the H+ ion of phenol are not liberated. but when phenolphthalein is treated with a base. the acidic part of phenol reacts with the base to give corresponding sodium salt of phenolphthalein which has pink color thus it imparts pink color to the solution Thus in acid base titration phenolphthalein is used to detect end point of base.MyeTutors-Home
Equation of how borax ions form when dissolved in water?
+1 to Rexy -1 to Joshua.. probably a bot or just answered the wrong question. echo the clarification? acetate or alcohol? Links below show the chemical breakdowns of the chains, and how adding borax creates cross-linked chains and can trap some water. You wind up with a Newtonian fluid. edit: NON-newtonian.. that just didn't look right Science is FUN!
How much water of crystallisation is present in borax?
Borax - Na2B4O7.10H2O(formula)It has 10 H2O (hydrated water)
What is the balanced chemical equation of copper oxide and nitrick?
I assume that you mean the reaction between copper oxide and nitric acid.As noted by Professor Kuppusamy,CuO + 2HNO3(a) = Cu(NO3)2 + H2O(l)Change in Free Energy: ΔG(20C) = -18.0kJ (negative, so the reaction runs)Change in Enthalpy: ΔH(20C) = -57.9kJ (negative, so the reaction is exothermic)
Equation for reaction between borax and hydrochloric acid???...URGENT?
Hi :) I would just like to know what is the molecular equation of the reaction between borax and hydrochloric acid and the states of all reactants and products?? I guessing its : Na2B4O7.10H2O + 2HCl --> 4H3BO3 + 2NaCl + 5H2O but what are the states of each reactant and product?? all answers are appreciated...10 POINTS FOR BEST ANSWER thanks :D
