Conjugate acids

Postby Adam Kramer 1A » Sun Dec 01, 2019 10:10 am

How can we find the conjugate acid or base in a solution?

The conjugate acid, in the products, is the compound that receives the proton and the conjugate base is the one that had given up the proton in the reactants. For example, with the equation, H2SO4 + H20 -> H30+ + HSO4-, the acid would be the H2SO4, the base would be H20, the conjugate acid would be H30+, and the conjugate base would HSO4-.

The conjugate acid receives the proton, and the conjugate base donates the proton.

The conjigate acid is the molecule that gains a proton when a base is added into a solution
Ex. NH3 + H20 -> NH4+ + OH-

The rxn can be broken down like this, respectively:

base + acid -> conjugate acid + conjugate base

In this rxn H20 acts as an acid though it has a neutral pH. Water can act as an acid or a base depending on the rxn.
