1. Reactions of Acids

2. 3 reactions to know Acid + Metal  SALT + Hydrogen
Acid + BASE  SALT + Water
Acid + Metal carbonate  SALT + Water + CO2

3. A BASE is a metal oxide or metal hydroxide
for example, gold oxide, magnesium hydroxide, sodium hydroxide
A base that dissolves in water is called an ALKALI
A SALT is an ionic compound
Formed from a METAL and a NON-METAL
From the metal, base
or carbonate
From the acid

4. Metal examples Acid + Metal  SALT + Hydrogen
Calcium + hydrochloric acid  ______________ ________
Calcium chloride
Hydrogen
Iron + hydrochloric acid  ______________ ________
