Bases
A base, or alkali, is a material that can donate a hydroxide ion (OH-)
Bases accept protons

Neutralization
Acids are paired with bases
The neutralization of an acid and a base produces water and a salt.
Proton Exchange between Water Molecules
A proton leaves the first molecule and is accepted by the second. The first becomes a base and the second becomes an acid. The acid then donates a proton and the
base accepts the proton.
Ph
A neutral pH can be achieved by adding an equal amount of the acid solution to the base solution
