Programming Problem

Chemists, biologists, and biochemists, are often interested in calculating the pH level of a given solution. A solution with a pH level less than 7 is acidic; otherwise, it is basic. Determining the pH of a solution is important, since many organisms and micro-organisms can only live in a limited pH range.
