# Are carboxylic acids strong acids?

May 14, 2016

No, the equilibrium lies to the left.

$R C \left(= O\right) O H + {H}_{2} O r i g h t \le f t h a r p \infty n s R C \left(= O\right) {O}^{-} + {H}_{3} {O}^{+}$

#### Explanation:

As acids go, carboxylic acids are fairly weak species, and acidity decreases as the length of the alkyl chain increases. See the table on this site for representative values.
