In the laboratory you are given the task of separating Agt and Pb2 ions in aqueous it can, write the formula of the precipitate. If it cannot, write No. a. Na2S04 b. NaOH c. KI d. Nal e. K2SO4

Explanation / Answer

(19)

Net ionic equation is:

Pb2+(aq) + S2-(aq) ---> PbS(s)

(20)

Net ionic equation is:

Co2+(aq) + CO32-(aq) ---> CoCO3(s)
