Question

complete the following reaction: C) Hydrochloric acid is sprinkle on calcium sulphide​

Answer 1

Answer:

Calcium Sulphate+ water

Sulphuric acid+ Calcium hydroxide → Calcium sulphate + Water

H

2

SO

4

→2H

+

+SO

4

2−

As H

2

SO

4

gives H

+

in water, it is an acid (Arrhenius Theory)

Ca(OH)

2

→Ca

2+

+2OH

−

As Ca(OH)

2

gives OH

−

in water, it is a base (Arrhenius Theory)

Hence it is a neutralization reaction.

Neutralization equation:

Acid+Base →Salt+water

so, the net equation will be:

2H
