I know that pure liquids and solids are omitted from equilibrium expressions, so how would I write an expression if the only product is a pure solid?  1/[reactants]  ??

3Ag+(aq) + PO4  3- (aq) Leftwards Arrow-> Ag3PO4 (s)
expression for equilibrium constant (oops)

What a weird equation!  There is no such molecule as PO4.  and what does '3 minus (aq)' mean?  Negative aqueous?  

Anyway, I'd write it like this

3Ag+(aq) + PO4 3- (aq) Leftwards Arrow-> Ag3PO4 (s) +XH2O

and then I'd complain to my teacher that this equation is not IUPAC friendly.

update:  Oh, haha, I get it now.  Duh Slight Smile  The 3- is the charge.  I'd still write the eq the same way, but I wouldn't complain to my teacher.

If you're doing an equilibrium equation where the only product is a solid, you would do 1/[reactants]. Since solids and liquids aren't included you would simply have a denominator.
Kc=1/[PO4 3-][Ag +]^3
