Question

Which salt is produced when sulfuric acid and calcium hydroxide react completely?

(1) CaH2 (3) CaS
(2) CaO (4) CaSO4

Answer 1

CaSO4 is produced when sulfuric acid and calcium hydroxide react completely.

Answer 2

Answer: Option (4) is the correct answer.

Step-by-step explanation:

When sulfuric acid reacts with calcium hydroxide then it results in the formation of calcium sulfate and water.

The chemical reaction for the same will be as follows.

`H_(2)SO_(4) + Ca(OH)_(2) \rightarrow CaSO_(4) + 2H_(2)O`

Thus, we can conclude that
`CaSO_(4)` salt is produced when sulfuric acid and calcium hydroxide react completely.
