Explanation:
Detailed explanation-1: -The pH of a weak acid generally lies in the range of 4 to 6 .
Detailed explanation-2: -The pH of a weak acid should be less than 7 (not neutral) and it’s usually less than the value for a strong acid. Note there are exceptions. For example, the pH of hydrochloric acid is 3.01 for a 1 mM solution, while the pH of hydrofluoric acid is also low, with a value of 3.27 for a 1 mM solution.
Detailed explanation-3: -The range goes from 0-14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
