Lesson 15

Applied Acid/Base Chemistry

Metal Oxides

Non metal Oxides

A) Aqueous solutions of metal and non-metal oxides

• Ionic Metal oxides basic– Group I and II except Be.

• Non metal oxides acidic

B) ACID RAINRain is slightly acidic pH around 5.6CO2 + 2H2O H3O+ + HCO3

-

Any precipitation with pH <5.6 is called Acid Rain.

Sources of Acidity:Most fuels ( coals and oil) are hydrocarbons that have sulphur; when sulphur is burnt…

B) ACID RAINSources of Acidity:

Combustion reactions esp. in automobiles produce..
