i) H 3 P O 4 ( a q ) ⇌ H + ( a q ) + H 2 P O 4 − ( a q )
ii)H 2 P O 4 − ( a q ) ⇌ H + ( a q ) + HPO 4 2 − ( a q )
iii)HPO 4 2 − ( a q ) ⇌ H + ( a q ) + PO 4 3 − ( a q )
The equilibrium constants for the above reactions at a certain temperature areK 1 , K 2 and K 3 respectively. The equilibrium constant for the reaction H 3 P O 4 ( a q ) ⇌ 3 H + ( a q ) + P O 4 3 − in terms of K 1 , K 2 and K 3 IS
