A combined numerical and experimental study is reported of a reactional melting of snow into solutions of sodium chloride, calcium chloride, and magnesium chloride. The numerical results are successfully validated through temperature decreases in the melting system. It is found that the temperature in the system quickly falls in a few seconds, and keeps an uniform temperature which denotes thermodynamical equilibrium. Although the maximum melting mass per unit volume of snow M_<max> is dependent on initial concentration C_<mi> and initial temperature T_i, M_<max> is not largely influenced by initial porosity or dry density of snow. Simple relationships are proposed to conventionally obtain the dimensionless maximum melting mass for each binary aqueous solution.
