Answer: The degree of ionization of a weak acid is greater than 50% but less than 100%.
Explanation:
An acid which dissociates partially or weakly when dissolved in water is called a weak acid.
For example, acetic acid [tex](CH_{3}COOH)[/tex] is a weak acid.
Hence, the degree of ionization of a weak acid is greater than 50% but less than 100%.
Thus, we can conclude that the degree of ionization of a weak acid is greater than 50% but less than 100%.
