Assume that you were assigned BaCl2 in lab. The water in your test tube weighed 24.823 g. Following the procedure in the lab manual, you determined that freezing point of water is 0.12oC. You weighed out 1.062 g of salt and added it to the original test tube, then determined that the freezing point was -0.38oC. Based on these experimental parameters, calculate the van't Hoff factor for BaCl2. Note that these are made-up numbers, and do not reflect a true experiment. Report your answer to two places after the decimal.

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.
