Question

Predict the type of salts formed by the reaction between $H_2{SO}_4$ and $Ca{\left(OH\right)}_2$.

• A. Normal salt
• B. Acidic salt
• C. Basic salt
• D. Both $\left(A\right)$ and $\left(B\right)$

Answer 1

The correct option is B Acidic salt

When $H_2{SO}_4$ and $Ca{\left(OH\right)}_2$ are mixed:
$H_2{SO}_4+Ca{\left(OH\right)}_2\to Ca{\left(SO\right)}_4+H_{2}O$
As $H_2{SO}_4$ is a strong acid and $Ca{\left(OH\right)}_2$ is a weak base. Therefore, $H_2{SO}_4$ will dominate its acidic character and the salt formed is acidic salt in nature.
