Homework Answers
Lower the pH , stronger is the acid.
HCl is a strong acid because it dissociates almost completely in solution and gives a larger concentration of H+ ion , hence HCl will have a lower pH.
CH3COOH is a weak acid because it dissociates partially in solution and gives smaller concentration of H+ ion , hence CH3COOH will have a higher pH.
Answer -- True
