Mark each as Saturated or Unsaturated:

1. 2.00 g of PbCl\(_2\) at 80°C

2. 100.2 g of NaNO\(_3\) at 60°C

3. 128 g of KI at 0°C

4. 75.5 g of LiCl at 20°C

5. 8.22 g of Ba(OH)\(_2\) at 40°C

Answer :

Answer:

1) unsaturated

2) unsaturated

3) saturated

4) unsaturated

5) saturated

Explanation:

A solution with solute that dissolves until it is unable to dissolve anymore, leaving the undissolved substances at the bottom., is called saturated. Each solution has a certain amount of mass that can dissolve at certain temperature.

A solution with less solute than the saturated solution, that completely dissolves, leaving no remaining substances., is called unsaturated.

A solution ,with more solute than the saturated solution, that contains more undissolved solute than the saturated solution, is called oversaturated.

A) 2.00 g of PbCl2 at 80°C

⇒ At 80 °C this solution is saturated when there is 2.54 grams of PbCl2 in solution

2.00 < 2.54 This solution is unsaturated

B) 100.2 g of NaNO3 at 60°C

⇒ At 60 °C this solution is saturated when there is 122 grams of NaNO3 in solution

100.2 < 122

This solution is unsaturated

C) 128 g of KI at 0°C

⇒ At 0 °C this solution is saturated when there is 128 grams of KI in solution

This solution is saturated

D) 75.5 g of LiCl at 20°C

⇒ At 20 °C this solution is saturated when there is 83.5 grams of LiCl3 in solution

75.5 < 83.5

This solution is unsaturated

E) 8.22 g of Ba(OH)2 at 40°C

⇒ At 40 °C this solution is saturated when there is 8.22 grams of Ba(OH)2 in solution

This solution is saturated
