Detailed explanation-1: -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-2: -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-3: -All substances can be classified as neutral (with a pH of about 7), basic (pH greater than 7), or acidic (pH less than 7), and the pH tells us how strong or weak that substance is as well. For example a substance with pH = 8 is a very weak base, but a substance with pH = 3 is a strong acid.
Detailed explanation-4: -Strong bases on the other hand have a pH close to 14 while weak bases have a pH just above 7.
Detailed explanation-5: -The solutions with pH values between 7 and 14 are basic in nature.
