Question

Which solution is considered saturated at 50°C when 50 g of solute is able to dissolve in 100 g of water?

A. KClO_3
B. NH_4Cl
C. KCl
D. NaNO_3

Answer 1

The solute that would be able to dissolve in 100 g of water at 50°C is KClO3 (option A), as its solubility is higher than 50 g.The solution that is considered saturated at 50°C when 50 g of solute is able to dissolve in 100 g of water is KClO3.

Step-by-step explanation:

A solution is considered saturated when it contains the maximum amount of solute that can dissolve in a given amount of solvent at a particular temperature. In this case, we have 50 g of solute (unknown) and 100 g of water. To determine which solution is saturated at 50°C, we need to compare the solubility of each solute.

Let's examine the solubility curves for each solute:

1. For KClO3, at 50°C, the solubility is approximately 70 g/100 g H2O.
2. For NH4Cl, at 50°C, the solubility is approximately 39 g/100 g H2O.
3. For KCl, at 50°C, the solubility is approximately 35 g/100 g H2O.
4. For NaNO3, at 50°C, the solubility is approximately 39 g/100 g H2O.

Based on the solubility values, the solute that would be able to dissolve in 100 g of water at 50°C is KClO3 (option A), as its solubility is higher than 50 g.
