Question

What is in solution which shows yellow turbidity, when hydrogen sulphide is passed in some oxidizing solution?

• A. Collidal solution of sulphur.
• B. Solution of reduced agent
• C. Solution of aques. sulphur trioxide.
• D. None of the above

Answer 1

Answer: (A)

Collidal solution of sulphur.

Collidal solution of sulphur shows yellow coloured turbidity,when $H_{2}S$ is passed in oxidising solution.

Oxidation - A colloidal solution of sulphur is obtained by passing $H_{2}S$ in a solution of $S{O}_2$ as - $2H_{2}S+S{O}_2\to 2H_{2}O+S{O}_2$
