What is the formula for potassium phosphite?
K3PO3
KPO4
K3PO4
KPO3
the phosphite in has the following formula PO33- I.e in this the oxygen is less when compare with PO43- so it is named as phosphite having the -3 charge
the potassium has the +1charge
to neutralize the -3 the three potassium ions are required so the formula is as follows 3K+ ions and one PO33-
answer = > K3PO3
