15 ml of satuated solution of potassium chloride in water at 50 degrees celecius is raised to 70 degrees celecius. How much more kcl will dissolve

To calculate how much more KCl will dissolve when the temperature is increased from 50°C to 70°C, we need to know the solubility of KCl at both temperatures.

The solubility of a substance generally increases with temperature. However, to accurately determine the amount of KCl that will dissolve, we need specific solubility data at the given temperatures.

If we assume that the saturated solution at 50°C is already at its maximum solubility, we can assume that no more KCl will dissolve when the temperature increases to 70°C. This is because the saturated solution already contains the maximum amount of KCl that can dissolve at 50°C.

Therefore, in this case, the amount of KCl that will dissolve when raising the temperature from 50°C to 70°C is zero.
