Question

Using the solubility curve, if 15g of potassium chlorate dissolves in 50 ml of water at 50 degrees Celsius, the solution is

Answer 1

We are given the solubility curve of KClO₃.

According to the curve at 50 °C the maximum amount that we can dissolve is 25 grams of KClO₃ in 100 ml of water (or 100 g what is the same). That means that in 50 ml of water we can only dissolve 12.5 g of KClO₃.

Answer: if 15 g of of KClO₃ dissolves in 50 ml of water at 50 °C, the solution is supersaturated.
