When a solution of HF (a weak acid) is added to a solution containing HPO₄^2- (here, a base), the equation for reaction that occurs is:

Question

Quizplus · Accepted Answer

The equation for the reaction between HF (a weak acid) and HPO4 2- (a base) is: 
HF + HPO4 2- -> H2PO4- + F-
This is an acid-base neutralization reaction, where the weak acid HF donates a proton to the base HPO4 2-, forming the conjugate acid H2PO4- and the conjugate base F-. Choice B correctly represents this equation.
