Explanation:

Step1: Locate sodium nitrate curve

Find the $NaNO_3$ curve on the solubility - curve graph.

Step2: Find solubility at 20°C

Locate the temperature of 20°C on the x - axis and then find the corresponding y - value on the $NaNO_3$ curve. The solubility of $NaNO_3$ in 100 g of water at 20°C is 88 g.

Step3: Locate potassium nitrate curve

Find the $KNO_3$ curve on the solubility - curve graph.

Step4: Find temperature for 110 g solubility

Locate 110 g on the y - axis (grams of solute per 100 g of $H_2O$) and then find the corresponding x - value (temperature) on the $KNO_3$ curve. The temperature is 60°C.

Step5: Locate ammonium chloride curve

Find the $NH_4Cl$ curve on the solubility - curve graph.

Step6: Find solubility at 50°C

Locate 50°C on the x - axis and then find the corresponding y - value on the $NH_4Cl$ curve. The solubility of $NH_4Cl$ in 100 g of water at 50°C is 50 g.

Step7: Locate sodium chloride curve

Find the $NaCl$ curve on the solubility - curve graph.

Step8: Find temperature for 40 g solubility

Locate 40 g on the y - axis and then find the corresponding x - value on the $NaCl$ curve. The temperature is approximately 100°C.

Step9: Locate potassium iodide curve

Find the $KI$ curve on the solubility - curve graph.

Step10: Find solubility at 10°C

Locate 10°C on the x - axis and then find the corresponding y - value on the $KI$ curve. The solubility of $KI$ in 100 g of water at 10°C is 135 g.

Step11: Locate sulfur dioxide curve

Find the $SO_2$ curve on the solubility - curve graph.

Step12: Find temperature for 10 g solubility

Locate 10 g on the y - axis and then find the corresponding x - value on the $SO_2$ curve. The temperature is approximately 50°C.

Answer:

1. 88 g
2. 60°C
3. 50 g
4. 100°C
5. 135 g
6. 50°C
