A) \[{{H}_{3}}P{{O}_{3}}\] is dibasic and reducing
B) \[{{H}_{3}}P{{O}_{3}}\]is dibasic and non-reducing
C) \[{{H}_{3}}P{{O}_{3}}\] is tribasic and reducing
D) \[{{H}_{3}}P{{O}_{3}}\] is tribasic and non-reducing
Correct Answer: A
Solution :
In \[{{H}_{3}}P{{O}_{3}},\] there are two OH- groups i.e. there are two ionisable protons. So it is diabasic in nature. The hydrogen which is directly attached to phosphorus atom is called as reducing hydrogen. As \[{{H}_{3}}P{{O}_{3}}\] contains one P-H bond it acts as a reducing agent.You need to login to perform this action.
