If 100 grams of a saturated solution of lead nitrate is cooled from 60c to 20c, what will happen

Answers

Answered by DrBob222
Some of the Pb(NO3)2 will crystallize since the solubility is less at 20C that at 60C.

100g of Pb(NO3)2 dissolve 0.297moles. 1000g of Pb(NO3)2 will dissolve 0.297*1000/100=2.97 mol/dm3
