Question

2KI + Pb(NO3)2 ---- 2KNO3 + PbI2 into Total and Net ionic equations.​

Answer 1

I'm supposed to write the net ionic equation for

2KI + Pb(NO3)2 -> PbI2 + 2KNO3

and I get how to do it for single replacement reactions but I don't understand writing a net ionic equation for double replacement reactions.

Thanks.

Answer 2

Lead nitrate is soluble, so it gets written as ions. The same goes for potassium iodide and potassium nitrate
