Question

The colour of the precipitate formed by mixing the aqueous solution of sodium sulphate with barium chloride is

• A.
  red
• B.
  green
• C.
  yellow
• D.
  white

Answer 1

The correct option is D

white
The reaction between aqueous solutions of sodium sulphate and barium chloride is as follows:

$N{a}_{2}S{O}_4\left(aq\right)+BaC{l}_2\left(aq\right)\to BaS{O}_4\left(s\right)+2NaCl\left(aq\right)$

A white coloured precipitate of barium sulphate $\left(BaS{O}_4\right)$ is obtained.

Hence, the correct answer is option (d).
