When the ph level of a substance is between 7 and 14, it is considered a(n) a. acid b. solution c. base d. mineral

The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. If a pH is lower than 7 it indicates the solution is an acid. If it is above 7 it is a base or Alkaline. If a pH is a 7 it is neutral. Strong acids have lower pHs than weak acids and strong bases have lower pHs than weak bases. A neutral solution is neither an acid or base. It has a pH of 7. Scientists use a pH number to show the strength of an acid or base. A pH is measured by dipping litmus into a solution such as water or other substances. Chemicals that are very basic or acidic are called "reactive." Automobile batteries have acids which are reactive and contain a stronger form of some of the same acid that is in acid rain. Also, household drain cleaners often contain lye, a very alkaline that is reactive. Vinegar and lemon juice are acidic substances and laundry detergents and ammonia are basic. Pure water is neutral which means that it has a pH of 7.0. It is not reactive.

THEREFORE IT WOULD BE B) SOLUTION
