What is the conjugate base of HSO4-?
February 20th, 2023
##SO_4^(2-)##
Although it has a negative charge, it will never accept a ##H^+## to form ##H_2SO^4##(sulfuric acid) . That is because sulfuric acid is a strong acid and completely disassociates in water.
Therefore, the sulfate ion (##SO_4^(2-)##) is the conjugate base of ##HSO_4^-##.
