evaluate: station 1 1. a solution of potassium chlorate, kclo3, has 20 grams of the salt dissolved in 100 grams of water at 70 °c. 2. approximately how many more grams of the salt can be added to the solution before reaching the saturation point?

evaluate: station 1 1. a solution of potassium chlorate, kclo3, has 20 grams of the salt dissolved in 100 grams of water at 70 °c. 2. approximately how many more grams of the salt can be added to the solution before reaching the saturation point?

Answer

Explanation:

Step1: Locate solubility on graph

Find the solubility of KClO₃ at 70°C on the graph. The solubility curve of KClO₃ shows that at 70°C, the solubility of KClO₃ in 100 g of water is approximately 30 g.

Step2: Calculate additional amount

The current solution has 20 g of KClO₃ in 100 g of water. To reach saturation, we subtract the current amount from the saturation - amount. Let (x) be the additional amount of KClO₃. (x = 30 - 20).

Answer:

10 g
