When silver nitrate (agno3) dissolves in water, the temperature of the solution decreases. describe the relative magnitudes of hsolute + ehsolvent and hmix. explain your answer. the enthalpy of solution for agno3 is positive because the temperature of the solution decreases (the dissolution is endothermic).hsol = hsolute + hsolvent + hmixhsolute and hsolvent are endothermic because energy is required to overcome intermolecular forces and separate solute and solvent particles. hmix is exothermic because energy is released when intermolecular forces form between solute and solvent particles. if the overall enthalpy of solution is positive, then hsolute + hsolvent must be larger in magnitude than hmix.
