Detailed explanation-1: -This pH value of 7 is important because it indicates a neutral solution. All other substances are compared to this neutral point. Any solution that has a pH of less than 7 is considered acidic, and anything above a pH of 7 is basic.

Detailed explanation-2: -As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral-neither acidic or basic.

Detailed explanation-3: -If the pH of a solution is less than 7, the solution is called acidic; In an acidic solution, then, the concentration of hydrogen ions is greater than the concentration of hydroxide ions. if the pH is about 7, the solution is neutral; if the pH is greater than 7, the solution is called basic.
