Magnesium chloride is an important coagulant used in the preparation of tofu from soy milk. Its solubility in water at 20oC is 54.6 g/100 g. At 80oC, its solubility is 66.1 g/ 100 g. A mixture is made up of 16.2 g of magnesium chloride and 38.2 g of water at 20oC. a. Is the mixture homogeneous? If it is, how many more grams of magnesium chloride are required to make a saturated solution? If the mixture is not homogeneous, how many grams of magnesium chloride are undissolved? b. How many more grams of magnesium chloride are needed to make a saturated solution at 80oC?
