Question

Which of the following step/(s) is/are carried out during preparation of caustic potash?

• A. The reaction between potassium sulphate and baryta is carried out.
• B. The precipitated $BaS{O}_4$ is separated.
• C. The filtrate is evaporated in the silver basin.
• D. All of the above

Answer 1

The correct option is D All of the above

All of the above steps are carried out during the preparation of caustic potash.
The reaction between potassium sulphate and baryta is carried out.
Note: Baryta is $Ba(OH{)}_2$
$K_{2}S{O}_4+Ba(OH{)}_2\to BaS{O}_4\downarrow 2KOH$
The precipitated $BaS{O}_4$ is separated.
The filtrate is evaporated in the silver basin.
