Step 1
The enthalpy of solution, also known as the heat of solution, is the amount of heat absorbed or released when a substance dissolves in a solvent to form a solution. The enthalpy of solution is expressed as (ΔHsoln), where ΔH represents the change in enthalpy.
The entropy of solution, also known as the entropy of mixing, is the change in entropy that occurs when a solute dissolves in a solvent to form a solution. The entropy of solution is expressed as (ΔSsoln), where ΔS represents the change in entropy.
