The volume (in mL ) of 0 . 1NNaOH required to neutralise 10mLof0 ....

The volume (in mLmL)of0.1NNaOHof 0 . 1NNaOH required to neutralise10mLof0.1N10mLof0 . 1N phosphinic acid is ____________.

Correct answer

0

Step-by-step solution

Phosphinic acid is hypo phosphorous acid (H3PO2)\left({H}_{3}{PO}_{2}\right).

NaOH+H3PO2→NaH2PO2+H2ONaOH + {H}_{3}{PO}_{2} \to {NaH}_{2}{PO}_{2} + {H}_{2}O

For neutrization

(N1V1)acid=(N2V2)base{\left({N}_{1}{V}_{1}\right)}_{acid} = {\left({N}_{2}{V}_{2}\right)}_{base}

0.1×10=0.1×(VmL)NaOH0 . 1 \times 10 = 0 . 1 \times {\left({V}_{mL}\right)}_{NaOH}

VNaOH=10mL{V}_{NaOH} = 10mL
