Determine whether a solid forms when solutions containing the follow salts are mixed. If so, write the ionic equation and the net ionic equation.

Question

a: Na3PO4 and AgNO3
b: K2SO4 and Na2CO3
C: Pb(NO3)2 and Na2CO3
d: BaCl2 and KOH

Answer 1

You need to learn (read that memorize) the solubility rules. Here is a simplified set.

For a I know that Ag3PO4 is insoluble.
The net ionic equation is
3Ag^+(aq) + PO4^-(aq) ==> Ag3PO4(s)
For b I know that K2CO3 and Na2SO4 are soluble.

Answer 2

Determine whether a solid forms when solutions containing the following salts are mixed. If so, write the ionic equation and the net ionic equation.
