Detailed explanation-1: -A pH value of 7 is neutral, indicating that the substance or solution is neither acidic nor alkaline. In this case, the pH of a solution is tested, and it is found to be a basic solution. Since basic solutions must have a pH greater than 7, then the correct answer is option D. The measured solution has a pH of 9.
Detailed explanation-2: -pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
Detailed explanation-3: -A solution with a pH of 9 is basic in nature. The pH measures the hydrogen ion ( ) concentration.
Detailed explanation-4: -so pH 9 is 1000 times more basic than pH 6.
Detailed explanation-5: -A useful category of solutions measured by the pH scale may be represented by a range of 0 to 14. For Example: pH 0 to pH 2 is Strongly Acidic. pH 3 to pH 5 is Weakly Acidic. pH 6 to pH 8 is Neutral. pH 9 to pH 11 is Weakly Basic.
