Homework Answers
Q1.
a)
Pb+2 ions and Cl- ions will form PbCl2(s) solids, so expect precipitation (YES)
b)
the balanced equation
Na2CO3(aq) + CrI2(aq) --> 2NaI(aq) + CrCO3(s)
CrCO3 is not soluble so it forms precipitate
Q2.
Iron(ii) Bromide = FeBr2
Sodium Carbonate = Na2CO3
FeBr2(aq) + Na2CO3(aq) --> FeCO3(s) + 2NaBr(aq)
FeCO3(s) is not soluble, it form precipitate
