Define Strong and weak acids

 

Strong and weak acids

Strong acids:

Acids contain hydrogen. Some acids are better at producing

H⁺(aq) ions than others. These are called strong acids.

Strong acids split up (dissociate) almost completely in water.

Weak acids:

However, weak acids reach dynamic equilibrium.

The acid molecules split up, just like a strong acid.

But at the same time, the H⁺ ions and OH^- negative ions that are made join up again. They form the original acid molecules
