Question

What happens when you mix acid and base?

Answer 1

A chemical reaction by definition forms new chemicals (called the products) from the initial chemicals (called the reactants). It should make sense that the identity of the products formed depends on what reactants we start with. Adding an acid to a base is an example of a chemical reaction, so we should expect to see new products. Although there is a pattern to this type of reaction, ultimately the products formed depend on what acid and what base are used.

Answer 2

Acids are chemicals with a pH less than 7 that can donate a proton or H+ ion in a reaction. Bases have a pH greater than 7 and can accept a proton or produce an OH- ion in a reaction. If you mix equal amounts of a strong acid and a strong base, the two chemicals essentially cancel each other out and produce a salt and water. Mixing equal amounts of a strong acid with a strong base also produces a neutral pH (pH = 7) solution. This is called a neauturization and looks like 
HA + BOH → BA + H2O + heat
