Question

Sum of basicity of $H_{3}P{O}_4$, $H_{3}P{O}_3$ and $H_{3}P{O}_2$ is equal to:

• A. 3
• B. 4
• C. 5
• D. 6

Answer 1

Answer: (D)

6

Sum of basicity of $H_{3}P{O}_4$, $H_{3}P{O}_3$ and $H_{3}P{O}_2$ is equal to 6.

Basicity of $H_{3}P{O}_4$ is 3

Basicity of $H_{3}P{O}_3$ is 2

Baicity of $H_{3}P{O}_2$ is 1.

So Sum of basicity of $H_{3}P{O}_4$, $H_{3}P{O}_3$ and $H_{3}P{O}_2$ is equal to 6.(3+2+2=6).

Hence option D is correct.
