If 15.0g of KCL is added to 100.0g of water at 30.0 C, how much more must be added to saturate the solution
35 C
What is the solubility of KCl at 30 C?
To determine how much more KCl must be added to saturate the solution, we need to find out how much KCl can be dissolved in 100.0g of water at 30.0°C. This information can be found in a solubility table or chart.
Solubility of KCl in water is typically expressed in terms of grams of solute that can be dissolved in 100g of water at a specific temperature. Let's assume that the solubility of KCl in water at 30.0°C is 50.0g/100g.
Since you already have 15.0g of KCl dissolved in 100.0g of water, we need to determine how much more we can add until we reach the maximum solubility:
Maximum solubility - Current amount of KCl = Amount of KCl that can still be added
50.0g/100g - 15.0g/100g = 35.0g/100g
Therefore, we can add a maximum of 35.0g of KCl to the solution before it reaches saturation.
