Calculate the heat of neutralization by ...

Calculate the heat of neutralization by mixing `200mL` of `0.1 MH_(2)SO_(4)` and `200mL ` of `0.2 MKOH `if heat generated by the mixing is `2.3 kJ`.

Text Solution

Verified by Experts

`Meq. `of `H_(2)SO_(4)=200xx0.1xx2=40`
`(H_(2)SO_(4)` is dibasic `)`
`Meq. `of `KOH=200xx0.2=40`
`:. 40 Meq. Of H_(2)SO_(4)` and `40Meq.` of `KOH` on mixing gives heat `=2.3kJ`
`:. 1000meq. ` of `H_(20SO_(4)` and `1000Meq.` of `KOH` on mixing gives heat
`=(2.3xx1000)/(40)=57.5kJ`
