The solutions are mixed together to form a single solution. One contains 0.2 mol Pb(C2H3O2)2, , the second contains 0.1 mol Na2S, and the third contains 0.1 mol CaCl2.

a)Write the net ionic equation for the precipitation reaction or reactions that occur.

b) What are the spectator ions in the solution?

nali · Answer

how would i know which ions become a compound 

for example, Pb can be with S or Cl2 

how would i know the difference

No fear.... Kawaii is here

ookawaiioo · Answer

Pb(C2H3O2)2 + Na2S ----> PbS + Na(C2H3O2)
Pb(C2H3O2)2 + CaCl2 ---> PbCl2 + Ca(Pb(C2H3O2)2

I dont think there will be any spectator ions since 0.2 moles of the Pb(C2H3O2)2 reacted with all the other compounds. But im not sure tho.....sorry.
