Normality of \[\text{0}\text{.3 M }{{\text{H}}_{\text{3}}}\text{P}{{\text{O}}_{\text{4}}}\]solution is :

A) 0.3 N                                     

B) 0.4 N

C) 0.6N                                      

D) 0.9 N

Correct Answer: D

Solution :

\[\text{Normality = molarity}\times x\]\[x=\]number of replacable H atom or OH groups in a molecule In \[{{\text{H}}_{\text{3}}}\text{P}{{\text{O}}_{\text{4}}}\] (orthophosphoric acid) \[x=3\]
