A. Hydrochloric Acid Solution and pH 1. Write the balanced chemical reaction for the dissociation of the hydrochloric acid. 2. Refer to the procedure for A to determine the concentrations of the solutions of hydrochloric acid. Remember to use MiV1-MV. Show work for trial 1. 3. Calculate the theoretical pH of each hydrochloric acid solution. Recall that hydrochloric acid is a strong acid, suggesting complete dissociation, so that the equation pH log (HO) can be used (equation 3). Show work...
