Question

What is the basicity of the final hydrolyzed product (oxyacid) of $P_4{S}_{10}$?

• A. 3
• B. 2
• C. 4
• D. 10

Answer 1

Answer: (A)

3

The final hydrolyzed product (oxyacid) of $P_4{S}_{10}$ is $H_{3}P{O}_4$.

So, basicity of $H_{3}P{O}_4$ is 3.

$P_4{S}_{10}+16H_{2}O\to 4H_{3}P{O}_4+10H_{2}S$.

The basicity of the final hydrolyzed product (oxyacid) of $P_4{S}_{10}$ is 3.

Hence, option A is correct.
