If you do not know what products are enter reagents only and click "Balance". Hydrochloric acid is a major reservoir for chlorine radicals in the atmosphere. Metal carbonate compounds react with dilute acids and emit carbon dioxide gas. The Histidine accident An unknown quantity of an HCl or NaOH solution was “mistakenly” added to a 2.000 L of a 0.1242 M histidine solution. Reaction of Y with NaOH gives X. asked Sep 11, 2020 in Chemistry by AmarDeep01 ( 50.1k points) jee main 2020 The chemical equation allows us to calculate the concentration of a solution of HCl by titration with the base NaOH (where the concentration of NaOH is accurately known). The coefficients indicate the mole ratios! Conclusion. 2: NaOH(aq)+HCl(aq) --> NaCl(aq)+H2O(l) Delta H2= 55 Rxn. Through the formation of hydrogen-bonded complexes, water has a dramatic effect on the rate of this reaction. Neutralisation reactions are exothermic. (X) on acidification with HCl gives compound (Y). For example, the reaction of hydrochloric acid, HCl, with sodium hydroxide, NaOH, solutions produces a solution of sodium chloride, NaCl, and some additional water molecules. For example, sodium hydroxide (NaOH, a base) and hydrochloric acid (HCl) give sodium chloride—common salt—and water through the reaction NaOH + HCl-> NaCl + HOH (H2O). Calculating the limiting reactant, the change in enthalpy of the reaction, ∆H rxn, can be determined since the reaction was conducted under conditions of constant pressure ∆H rxn = q rxn / # moles of limiting reactant. Using phenolphthalein as indicator, 25 ml of mixture required 21 ml of 1.1 N HCl for the end point. Reaction Information.
