Detailed explanation-1: -A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value.
Detailed explanation-2: -The lower a substance’s pH, the more acidic it is. Each whole pH value below 7 (the neutral point) is ten times more acidic than the next higher value.
Detailed explanation-3: -pH is a measure of how acidic/basic water is. 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: -It ranges from 0 to 14. A pH of 7 is neutral, a pH less than 7 is acidic, and a pH greater than 7 is basic. Each whole pH value below 7 is 10 times more acidic than the next higher value, meaning that the concentration of hydrogen ions is 10 times as great.
Detailed explanation-5: -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.
