Magnesium chloride is an important coagulant used in the preparation of tofu from soy milk. its solubility in water at 200c is 54.6 g/100 g. at 800c, 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 200c.
(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 800c?
