The formula weight of an acid is `82.0.100 cm^(3)` of a solution of this acid containing `39.0 g` of the acid per litre were completely neutralised by `95.0 cm^(3)` of aqueous `NaOH` containing `40.0 g` of `NaOH` per litre. What is the basicity of the acid?

Text Solution

Verified by Experts

The correct Answer is:
2
`N_(NaOH) = 1, N_(a) = (1 xx 95)/(100) = 0.95`
`0.95 = (39)/(E) rArr E.Q = 41 :.` Basicity `= (82)/(41) = 2`
