An Intiative by Sri Chaitanya

${ΔH}_{soln} = {ΔH}_{3} - {ΔH}_{1} - {ΔH}_{2}$

${ΔH}_{soln} = {ΔH}_{1} + {ΔH}_{2} + {ΔH}_{3}$

${ΔH}_{soln} = {ΔH}_{1} - {ΔH}_{2} - {ΔH}_{3}$

${ΔH}_{soln} = {ΔH}_{1} + {ΔH}_{2} - {ΔH}_{3}$

answer is B.

Detailed Solution

For an ideal solution, ${ΔH}_{mixing} = 0$
$ΔH = {ΔH}_{1} + {ΔH}_{2} + {ΔH}_{3}$ (According to Hess's law)
i.e., for ideal solutions, there is no change in magnitude of the attractive forces in the two components present.
