How do I compare the strength of two acids?

You can compare the strength of two acids by comparing their acidity constants. small Ka values correspond to weak acids.

The strength of an acid is dependent on how likely it is to fully dissociate. Strong acids tend to fully deprotonate so their Ka value is higher. Weak acids do not dissociate as easily and their Ka values will be smaller in comparison.
