Indicator:

A substance that changes color at different pH levels and is used to signal when a reaction has reached its endpoint.

Neutralization Reaction:

A type of chemical reaction where an acid reacts with a base to produce water and salt. This is what happens during titration up until we reach our "finish line" or endpoint.
