0.4 gm of polybasic acid `H_(n)A` (M.wt = 96) requires 0.5 gm NaOH for complete neutralisation. The number of replacable hydorgen atoms are (all the hydrogens are acidic)

Text Solution

Verified by Experts

The correct Answer is:
3
m eq acid = M eq Base
`(0.4)/(Nw//n)xx1000=(0.5)/(40//1)xx1000impliesn=3`
