Title: Dissolution of Ag3PO4
Post by: kissoftalons on August 28, 2005, 10:27:49 PM
Could someone help me understand this problem and possibly point me in the right direction.

Write an Ionic equation for the dissolution of Ag3PO4(s) in water...

I am not sure what "dissolution" means..is it just dissolving?

I would guess the answer as:
Ag3-(aq) + PO4 3- (aq)

Is this correct?

Ag3PO4 -> 3 Ag+ + PO43-

Silver is positive, so you write +. It just has charge +1 and you need three times as much as PO3- which has a charge of -3.

dissolution.. for salts it refers to the dissociation into its component ions in a suitable solvent.
