Detailed explanation-1: -As this diagram shows, pH ranges from 0 to 14, with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).
Detailed explanation-2: -The numbers 8-14 on the pH scale indicate an alkaline solution. 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 pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.
Detailed explanation-4: -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.
Detailed explanation-5: -The solutions with pH values between 7 and 14 are basic in nature.
