State your basis and show calculations. (Kf,water = 1.86 K kg mol-1)  NaCl, MgCl2, and CaCO3 are candidate salts in the homemade ice cream-making process. The salts are to be dissolved in the ice-water mixture to lower the temperature of the mixture. The mixture will be then used to freeze ice cream. Which salt will be much more effective in lowering the temperature of the ice-water mixture considering that equal masses of each salt are to be compared?

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
