Question

For ideal solution the enthalpy of mixing of the pure components to form the solution is ____________.

Options

• None of these

• ΔH_mix = +ve

• ΔH_mix = −ve

• ΔH_mix = 0

Answer 1

For ideal solution the enthalpy of mixing of the pure components to form the solution is ΔH_mix = 0.

Explanation:

For the ideal solution, there is no evolution or absorption of heat on mixing.
