To determine the pH of commercially supplied 32% Hydrochloric acid solution.
Can the pH of an acid which is Hydrochloric acid be calculated by using titration with a standardized base solution of Sodium Hydroxide?
That the pH of the hydrochloric acid solution can be calculated using titration with a standardised sodium hydroxide base solution as long as concentration and temperature of base solution remain constant.
