Question: For $ H_3PO_3 $ and $ H_3PO_4 $ the correct choice is [IIT Screening 2003]
Options:
A) $ H_3PO_3 $ is dibasic and reducing
B) $ H_3PO_3 $ is dibasic and non-reducing
C) $ H_3PO_4 $ is tribasic and reducing
D) $ H_3PO_3 $ is tribasic and non-reducing
Show Answer
Answer:
Correct Answer: A
Solution:
$ H-O-\underset{O}{\overset{H}{\mathop{\underset{\downarrow }{\overset{|}{\mathop{P}}},}}},-OH $ , hence it is dibasic. It acts as reducing agent also.
