Question -

For $H_{3} P O_{3}$ and $H_{3} P O_{4}$ the correct choice is

Options:

A .

H_{3} P O_{3}

is dibasic and reducing

B .

H_{3} P O_{3}

is dibasic and non-reducing

C .

H_{3} P O_{4}

is tribasic and reducing

D .

H_{3} P O_{3}

is tribasic and non-reducing

Answer: Option A
:
A

$H - O - H | P ↓ O - O H$ , it can donate two hydrogen ion, hence called dibasic. It is reducing as by releasing hydrogen it gets oxidised and reduce other.
