Question

Quizplus · Accepted Answer

The mixture with household cleanser containing 0.5 M ammonia will have the highest pH after adding vinegar. This is because ammonia (NH3) is a weak base that reacts with the acetic acid in vinegar to form ammonium acetate, a weak salt, and water. This reaction partially neutralizes the acidity of the vinegar, resulting in a higher pH compared to the other mixtures. The other options involve either neutral or acidic solutions, which would not increase the pH as significantly as the basic ammonia solution.
