Homework Answers
The reaction is
a)
CH3COO- (aq) + H2PO4- (aq) <----------> CH3COOH (aq) + HPO4-2(aq)
BL base BL acid BL conjugate acid BL conjugate base
This is the net ionic equation.
b)The pKa of acetic acid is 4.74 and pKa of H2PO4- is 7.21 .
As the equilibrium always favors the side of weak acid- base pair, this equilibrium is shifted towards the reactants which are weak acid -base pair than the products.
