Abase is added to an acid during a titration. a ph meter is used to monitor the reaction’s progress. when should the addition of base stop? when adding a few drops of base causes a large decrease in ph when adding a few drops of base causes a large increase in ph when adding a few milliliters of base causes a large increase in ph when adding a few milliliters of base causes a large decrease in ph

The correct answer is'when adding a few drops of base causes a large increase in pH'.

Explanation:

When an acid reacts with base neutralization reaction occurs which means that  H^+ ions from the acid and OH^- ion from the base combine together to form neutral molecule of water.

During the titration , while adding base to an acid. Addition of base must be stopped when large increase in value of pH of an acid is observed on a pH meter.
