Heat capacity of solution = Solute + Solvent?

Is the heat capacity of a solution the sum of the heat capacities of the solvent and the solute?


Based on what I have learned, specific heat is determined by the interaction between molecules. This explains water's large specific heat because it has many hydrogen bonds which take a large portion of the supplied heat to break and only the rest actually increases the temperature.


When the solute dissolves into the solvent, I assume the bonds between the molecules strengthen, so the total heat capacity increases. Is this correct?


If I am correct, is the change in heat capacity negligible or significant enough to take into calculation?
