Question

In KJ/Mol, the heat evolved when 1mole of sulphuric acid react with sodium hydroxide is approximately

Answer 1

Answer:

114 kJ of heat.

Explanation:

Neutralization of a diprotic acid will produce more heat energy than a monoprotic acid.

○ Monoprotic acid + alkali

1 mole of HCl will react with 1 mole of NaOH to produce 57.0kJ of heat.

○ Diprotic acid + alkali1 mole of H2SO4 will react with 2 mole of NaOH to produce 114 kJ of heat.
