The solubility of Pb(NO₃)₂ is 55 grams per 100 g H₂O at 20°C.Which term would properly describe a solution where 44 grams of Pb(NO₃)₂ is added to 100 grams of water at this temperature?

Question

Quizplus · Accepted Answer

The solubility of Pb(NO₃)₂ is given as 55 grams per 100 g H₂O at 20°C. Since we are adding only 44 grams of the compound to 100 grams of water, the solution is unsaturated. If we had added 55 grams, then the solution would be saturated, and if we had added more than 55 grams, then the solution would be supersaturated. Therefore, the best choice is B, unsaturated.
