ANSWER
Weak acid
EXPLANATION
Firstly, we need to differentiate between weak acid and strong acid
Strong acid is a type of acid that ionize completely in an aqueous solution
Weak acid is a type of acid that ionize partially in an aqueous solution.
CH3COOH which is also known as acetic acid dissociate partially in an aqueous solution
[tex]\text{ CH}_3COOH\text{ }\rightarrow\text{ CH}_3COO^-\text{ + H}^+[/tex]
Therefore, CH3COOH is a weak acid
