Acids and Bases: React

Problem = too much stomach acid

Solution = add a base (antacid)

need an acid-base reaction

Bases react with acids to diminish, or neutralize their properties.

decomposition - a compound breaks down into simpler substances

single-displacement - one element takes the place of another in a compound

double-displacement - the positive portions of two ionic compounds are interchanged

combustion - a substance rapidly combines with oxygen to form one or more oxides

neutralization - properties of both the acid and base are neutralized when they react.

most cases: water & salt are result of acid/base reaction

Salt = general term used to describe the ionic compound formed from the negative part of the acid and positive part of the base.

Three of the four fundamental tastes are linked to acids and bases

buffer = a solution that resists changes in pH when moderate amounts of acids or bases are added.

blod - slightly basic (7.4)
