Detailed explanation-1: -The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value. For example, pH 10 is ten times more alkaline than pH 9 and 100 times (10 times 10) more alkaline than pH 8.

Detailed explanation-2: -The same holds true for pH values higher than 7, each of which is 10 times more alkaline than the next lower whole value. For example, pH 10 is 10 times more alkaline than pH 9 and 100 times (10 x 10) more alkaline than pH 8.

Detailed explanation-3: -A solution with a pH of 10 is 100 times more basic compared to a solution with a pH of 8. On a pH scale, one step represents ten times more or less basic a solution is.

Detailed explanation-4: -A solution with a pH of 10 is 100 times more basic than a solution with pH 8.

Detailed explanation-5: -pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).
