A) 40 mL
B) 20 mL
C) 10 mL
D) 60 mL
Correct Answer: A
Solution :
\[{{H}_{3}}P{{O}_{3}}\] is a dibasic acid \[{{N}_{1}}{{V}_{1}}\](acid) \[={{N}_{2}}{{V}_{2}}\] (base) \[0.1\times 2\times 20=0.1\times 1\times {{V}_{2}}\] \[\therefore \]\[{{V}_{2}}=\frac{0.1\times 2\times 20}{0.1\times 1}=40\,ml\]You need to login to perform this action.
