What is the difference between a weak acid and a strong acid?
assistant
The main difference between a weak acid and a strong acid is the degree of dissociation. A strong acid will completely dissociate into its component ions in water, while a weak acid will only partially dissociate. For example, hydrochloric acid (HCl), is a strong acid, while acetic acid (CH3COOH), is a weak acid. The more it dissociates, the stronger the acid is.
