One gram equivalent of a weak acid is unable to completely neutralise one gram equivalent of a strong base.

A

`-1120` cals

B

`-2110` cals

C

`1210` cals

D

`+1210 cals`

Text Solution

Verified by Experts

The correct Answer is:
3
`13960=-13680xx(3)/(4)-13680xx(1)/(4)+(1)/(4)x`
where x is enthalpy of dissociation/ionisation of weak acid.
so `x=1120` calories.
