Detailed explanation-1: -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-2: -That is, it has more OH-then H+ ions. Examples of a base would be baking sugar, ammonia, sea water, and lye. The numbers 8-14 on the scale are increasing alkalinity.

Detailed explanation-3: -The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral-neither acidic or basic.

Detailed explanation-4: -pH less than 7 is acidic, with 0 the most acidic. More than 7 is basic or alkaline, with 14 the most basic.

Detailed explanation-5: -pH of 11-14 is strong base/alkali.
