Here is a simplified set of solubility rules. You should memorize this table.

what is the complete and net ionic equation? I just done understand.... HELP please!
Answered by DrBob222
You should have the phase; since you don't I will add what I think is appropriate.
Na2CO3(aq) + NiCl2(aq) ==> NiCO3(s) + 2NaCl(aq)

2Na^+(aq) + CO3^2-(aq) + Ni^2+(aq) + 2Cl^-(aq) ==> NiCO3(s) + 2Na^+(aq) + 2Cl^-(aq)
This is the complete ionic equation. To make it a net ionic equation you go through and cancel ions that are the same on each side of the equation What is left is the net ionic equation. For example, there is a Cl^- on both side; cancel them. Etc.

So the net equation is CO3^2-(aq)+Ni^2+(aq)----->NiCO3(s)
