Heat of neutralization will be minimum for which of the following combination

Answer»

`NaOH+H_(2)SO_(4)`
`NH_(4)OH+CH_(3)COOH`
`NaOH+HCl`
`NaOH+CH_(3)COOH`

SOLUTION :Heat of neutralization is the heat liberated when one mole acid is neutralized by base. For strong acid-strong base neutralization, its VALUE is 57kJ/mol. For weak acid or base its value is less than this value. Hence, the heat of neutralization will be MINIMUM for `CH_(3)COOH+NH_(4)OH`.
