which amount of a compound dissolved in 110.g of water at the stated temperature represents a solution that is saturated?
(1)20g KClO3 at 80 C
(2)40g KNO3 at 25 C
(3)40 g KCl at 60 C
(4)60 g NaNO3 at 40 C
The answer is 2
2 if the H20 is at 100g not 110g - my bad :)
To determine which amount of compound dissolved in 110.g of water represents a saturated solution, we need to compare the solubility of each compound at the given temperature to the amount that is dissolved.
To solve this problem, we should consult a solubility chart. This chart provides the maximum amount of a compound that can dissolve in a given solvent at a specific temperature. The compound is considered to be soluble if the amount dissolved is less than or equal to the maximum solubility stated in the chart.
For each compound and temperature given, we can compare the amount dissolved to the maximum solubility:
(1) 20g KClO3 at 80°C:
Check the solubility chart for the maximum solubility of KClO3 at 80°C. If 20g is less than or equal to the maximum solubility, then the solution is saturated.
(2) 40g KNO3 at 25°C:
Check the solubility chart for the maximum solubility of KNO3 at 25°C. If 40g is less than or equal to the maximum solubility, then the solution is saturated.
(3) 40g KCl at 60°C:
Check the solubility chart for the maximum solubility of KCl at 60°C. If 40g is less than or equal to the maximum solubility, then the solution is saturated.
(4) 60g NaNO3 at 40°C:
Check the solubility chart for the maximum solubility of NaNO3 at 40°C. If 60g is less than or equal to the maximum solubility, then the solution is saturated.
By comparing the given amounts to the maximum solubilities for each compound at the respective temperatures, you can determine which of the options represents a saturated solution.
