2.0 g of polybasic organic acid (Molecular mass =600) required 100 mL of a `(M)/(6)` NaOH solution for complete neutralisation. Find the basicity of acid .

Text Solution

Verified by Experts

The correct Answer is:
5
meq of acid = meq of base `(g)/(E) xx 1000 = N_(b) xx V_(b)`
`rArr (2)/(600//x) xx 1000 = (1)/(6) xx 100 (N_(NaOH) = M_(NaOH)), " since x " = 1 rArr x = 5`
