A chemist finds a bottle of hydrochloric acid in his laboratory. Although the chemical is labeled properly, the concentration is not included. He decides to determine the concentration of the acid by performing an acid-base titration reaction. To perform this reaction, he adds a known volume and concentration of strong base to the acid while measuring the pH of the combined acid and base. Once a neutral pH is obtained, the reaction has proceeded to completion, and the concentration of the acid may be calculated. In this reaction, what is the dependent variable?

The dependent variable is the pH of the reaction mixture. Signup and view all the answers
