Help with net ionic equations

[denavious]

Can someone help me with complex net ionic equations and clearify solubility rules for me!

ex of type of problems:

A solution of potassium iodide is added to an acidified solution of potassium dichromate.

[sdekivit]

KI + acidified K2Cr2O7

--> acidified dichromate is a strong oxidator and so you should build a redoxreaction by setting up 2 halfreactions

(You should also remember that acidified permanganate is also most of the times a redoxreaction )
