easy notes to learn for chemistry! in preparing common salts.

2. 1. From Hydrochloric Acid (HCL).
 Sodium chloride
 Calcium chloride . Etc
2. From Sulphuric Acid.
 Zinc sulphate. Etc.
3. From Nitric Acid.
 Cobalt nitrate. Etc.

3.  Salt that forms white crystals.
 Used to absorb moisture from the air and is known as
a drying agent.
 Also used in food processing, medicine and in
speeding up the setting of concrete.

4.  Forms white crystals.
 Used in making cosmetics, few deodorants,
textile materials _ rayon and glue and in
bleaching paper.
 Also used as a herbicide and in treatment of
sewage.
 Used by chemists in investigations of
substances to find their chemical components.

5. Zinc is used as components of cosmetics
as it protects the skin when used in
creams for treatment of acne and as an
acid for healing skin after its burned.

7.  Hydrochloric Acid.
 Sulphuric Acid.
 Nitric Acid.
Salts produced by these acids
 Hydrochloric acid _ chlorides
 Sulphuric Acid _ sulphates.
 Nitric Acid _ nitrates.

8. Common salts can be prepared from a Metal
or Acid.
 Substances with a pH of more than 7 are
alkalis or bases.
 Neutralization is the specific term used for the
reactions of acids with alkalis or bases.
 Calcium chloride is used to absorb moisture
from the air.
