Solution: Consider the reaction below.H2PO4- + H2O → H3O+ + HPO42-Which of the following is a base-conjugate acid pair?

Solution: Consider the reaction below.H2PO4- + H2O → H3O+ + HPO42-Which of the following is a base-conjugate acid pair?

Problem

Consider the reaction below.

H2PO4- + H2O → H3O+ + HPO42-

Which of the following is a base-conjugate acid pair?

Solution

We have to determine which of the species make up a base-conjugate acid pair.

Conjugate acids and bases are a part of the Brønsted-Lowry acid-base theory.

  • This theory is based on the transfer of protons.
  • A base is a proton acceptor.
  • A base gains a positive charge by the gain of a proton.
  • The specie formed after the gain of a proton by a base is called its conjugate acid.
