Daily Uses of Neutralization?

Question

Do any of you guys know any daily uses of neutralization? May I have four examples?

Answer 1

When someone takes a Tum for acid indigestion.

The hydrochloric acid in your stomach is neutralized when it goes into your small intestine

when baking soda is used as a leavening agent( to make the cake rise) it must have an acid ingredient to release the CO2 gas. This does also neutralize the acid

When acids that are used in industry and must be disposed of, they must be neutralized. This also goes for any acid spill.
