Differentiate between acids and bases on the basis of their pH values.

acid; there ph value is mostly 7

base: there ph value can be more than 7 or less than 7

The more towards 0 a pH value is, the increasingly acidic. Conversely, the more towards 14 a pH value is, the increasingly alkaline. Some examples of bases are lye, ammonia, and seawater. Some examples of acids are vinegar, lemon juice, and battery acid. To determine the pH of a liquid, you can use pH strips. Depending on the color (the redder the more acidic, the bluer the more alkaline), you can determine the pH of whatever you are trying to measure.
