## Conjugate?

Acidity $K_{a}$
Basicity $K_{b}$
The Conjugate Seesaw $K_{a}\times K_{b}=K_{w}$

### Conjugate?

Can someone give an example of conjugates of an acid and base in a chemical equation form?

A conjugate base is just the acid without one of the hydrogens. For example, the conjugate base to H2SO4 is HSO4-.
A conjugate acid just the base with an additional hydrogen. For example, the conjugate acid to CN- is HCN.

A conjugate base is the result of an acid donating its protons.
A conjugate acid is the result of a base accepting protons.

In the reaction Ba(OH)2 + H2O = Ba + 2OH + H2O, the conjugate base is H2O and the conjugate acid is OH. Whatever was the base before the reaction becomes the conjugate acid and whatever was the acid before the problem becomes the conjugate base.

Thanks for the explanation, I kept confusing which was which

CH3COOH + H20 = H3O^+ + CH3COO^-

In this reaction, CH3COOH is the acid because it is donating a proton. Its conjugate base is CH3COO-. Water in this reaction acts as a base since it is receiving a proton, making its conjugate base to be H3O+.
