What occurs when sodium hydroxide and hydrochloric acid are mixed Question #1ddf0 How many milliliters of sodium hydroxide must be added to 75 mL of N hydrochloric acid to make a neutral solution
Stoichiometry is the chemistry that mathematically relates all substances in a reaction quantitatively relating the amount of reactants and products in a chemical reaction It allows the chemist to determine the amount of product that will form from a given amount of reactants or the amount of one reactant that is needed to react completely with some specific amount of the
2 Since the pH of the mixed solution is neutral pH = 7 we have no hydroxide ion other than that present at pH = 7 in the solution Since HCl and NaOH react in a 1 1 molar ratio that means that mmol of HCl was added 3 What is the concentration of the HCl mmol / 100 mL = M Since HCl is a strong acid the [H ] = M
