Explanation:
Detailed explanation-1: -A solution of pH 3 will have 100 times more H+ (it is 100 times more acidic) than a solution of pH 5.
Detailed explanation-2: -Detailed Solution Conclusion: So, from the above explanation, it is clear that the Higher the pH, the weaker is the acid, and the Lower the pH, the weaker is the base.
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.
Detailed explanation-4: -pH is the negative logarithm of hydrogen ion concentration in a solution. It tells us about the strength of an acid.
