Calcium chloride (CaCl2) is sometimes used for this purpose too. Let us compare the effectiveness of equal masses of these two compounds in lowering the freezing point of water, by calculating the freezing point depression of solutions containing 200. g of each salt in 1.00 kg of water.

A disadvantage is that this compound is more costly.)arrow_forwardSamples of each of the substances listed below are dissolved in 125 g of water. Which of the solutions has the highest boiling point?
