Answer & Solution

Correct Answer

(C) \(10\)

Step-by-step Solution

Detailed explanation

\(H _{3} PO _{2}+ NaOH \rightarrow NaH _{2} PO _{2}+ H _{2} O\) \(\frac{ n _{ H_3 PO _{2}} \text { reacted }}{1}=\frac{ n _{ NaOH } \text { reacted }}{1}\) \(\Rightarrow \frac{0.1 \times 10}{1}=0.1 \times V _{ NaOH }\) \(\Rightarrow V _{ NaOH }=10 ml\)
