A 68.4g sample of Potassium Chloride was added to 200g of water at 20 degrees celsius. Is the solution saturated, unsaturated, or supersaturated?
Answer?
Saturated for future reference
To determine whether the solution is saturated, unsaturated, or supersaturated, we need to compare the solubility of Potassium Chloride (KCl) in water at 20 degrees Celsius with the amount of KCl that is actually dissolved in the solution.
1. Look up the solubility of Potassium Chloride: The solubility of KCl in water at 20 degrees Celsius is approximately 34.2 grams per 100 grams of water.
2. Calculate the maximum amount of KCl that can be dissolved in 200 grams of water at 20 degrees Celsius:
Maximum amount of KCl = (34.2 g KCl / 100 g water) * (200 g water)
= 68.4 g KCl
Since the amount of KCl in the sample (68.4 g) is equal to the maximum amount that can be dissolved in the given amount of water, the solution is considered saturated.
Therefore, the solution is saturated.
