If 20 g KCl is dissolved in 100g of water at 20 degrees C, is the solution unsaturated, saturated, or supersaturated?

This solution is saturated because it can further dissolve 14.2 g KCl at 20*C , it will because maximum solubility of KCl at 20*C is 34.2 g
So sorry I meqn this solution is unsaturated ,, again sorry for inconvenient
To determine whether the solution is unsaturated, saturated, or supersaturated, we need to compare the amount of solute dissolved to the maximum amount that can be dissolved at a given temperature. In this case, we have 20 grams of KCl dissolved in 100 grams of water at 20 degrees Celsius.
One way to find out if the solution is unsaturated, saturated, or supersaturated is to check the solubility of KCl at 20 degrees Celsius. We can look up the solubility of KCl in a reference book or search for it online.
Let's assume that the solubility of KCl at 20 degrees Celsius is 30 grams per 100 grams of water.
Since we dissolved 20 grams of KCl in 100 grams of water, the solution is not saturated because it does not contain the maximum amount of solute that can be dissolved at that temperature. It is considered unsaturated.
If the amount of solute dissolved had reached the maximum solubility value or exceeded it, then the solution would be saturated or supersaturated, respectively.
