Question

heat of neutralization of strong diabasic acid in dilute solution of NaOH is nearly

Answer 1

Since NaOH has valency factor of 1 and dibasic acid has valency factor of 2 ,then only 1 gram equivalent of dibasic acid is neutralised by 1 gram equivalent of NaOH .this the amount of heat released will be 57.1 KJ/mol-1 or 13.7 kcal/equivalent ........
