Reversibility of a chemical change
To determine whether the solutes dissolved in 100g of water will form an unsaturated or saturated solution, we need to compare the amount of solute dissolved to the maximum amount that can be dissolved at the given temperature. If the amount dissolved is less than the maximum amount, it is an unsaturated solution. If the amount dissolved is equal to the maximum amount, it is a saturated solution.
a. 180g Kl at 60 degrees Celsius:
To find out if this solute will form an unsaturated or saturated solution, we need to know the solubility of Kl at 60 degrees Celsius. This information can be found in a solubility chart or table. Let's assume that the solubility of Kl at 60 degrees Celsius is 150g/100g-water.
Since the solubility of Kl is 150g/100g-water and we have 180g Kl, which is greater than 150g, this solution is saturated.
b. 60g KBr at 30 degrees Celsius:
Similar to the first case, we need to find the solubility of KBr at 30 degrees Celsius. Let's assume the solubility is 80g/100g-water.
Since we have 60g KBr, which is less than the solubility of 80g, this solution is unsaturated.
c. 170g KNO3 at 50 degrees Celsius:
Again, we need to determine the solubility of KNO3 at 50 degrees Celsius. Let's assume the solubility is 200g/100g-water.
Since we have 170g KNO3, which is less than the solubility of 200g, this solution is unsaturated.
d. 20g NaCl at 90 degrees Celsius:
Once more, we need to determine the solubility of NaCl at 90 degrees Celsius. Let's assume the solubility is 50g/100g-water.
Since we have 20g NaCl, which is less than the solubility of 50g, this solution is unsaturated.
