4. An acid is a chemical compound which is soluble in water,
tastes sour and turns blue litmus paper pink. Acids
neutralize bases. Acids may be divided into two
groups, strong acids and weak acids. Many weak
acids occur naturally in foods and can be eaten like citric
acid and lactic acid. Strong acids are corrosive and should
not be tasted, E.g. Hydrochloric acid.

4. 5.1.Sulphuric acid (cleaner & battery)
2.Citric acid (jellies & jams)
3.Acetic acid (Vinegar & ketchup)
4.Ascorbic acid (citrus fruits)
5.Lactic acid (Milk products)

6. A base is the opposite of an acid. As seen on
the pH scale, bases describe solutions with a pH greater
than 7, and there is a range of how basic a solution can
be. Bases turn red litmus paper blue. They tend to taste
bitter and feel slippery. They are capable of reacting
with an acid to form a salt.

2. Household Ammonia
3. Oven cleaner
4. Soap
5. Milk of Magnesia
6. Antacid medications

8. In chemistry, salts are ionic compounds that are formed
from the neutralization reactions of an acid and a base.
Salts are made up of an equal number of anions (positive
ions) and cations (negative ions). They are hard and
brittle. Most salts dissolve in water and are solids at room
temperature. They have strong bonds and a relatively
high boiling point.

2. Table salt (sodium chloride)
3. Powder bleach (calcium oxychloride)
4. Baking soda (bicarbonate of soda)
5. Washing soda (Sodium carbonate)
