The solubility of sodium chloride and potassium chlorate are the same at
57 °C
80 °C
96 °C
At 57 °C, the solubility of both sodium chloride and potassium chlorate is the same.
At 80 °C, the solubility of both sodium chloride and potassium chlorate is the same.
At 96 °C, the solubility of both sodium chloride and potassium chlorate is the same.
These temperatures represent the saturation point for both sodium chloride and potassium chlorate, meaning that the maximum amount of each substance that can dissolve in a given amount of solvent at these temperatures is the same.
