Detailed explanation-1: -The pH of a neutral solution is 7. Acidic solution is represented by a value less than 7 on the pH scale. Whereas basic solution is represented by a value greater than 7 on the pH scale.
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. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
Detailed explanation-3: -It happens that at pH 7, the concentrations of H+ and OH-are equal. This is why pH 7 is considered the neutral pH. Below pH 7, the concentration of H+ is greater than the concentration of OH-, making the water acidic. Above pH 7, the concentration of OH-is greater than the concentration of H+, making the water basic.
Detailed explanation-4: -pH<7: acidic solution. pH>7: basic solution. pH=7: neutral solution.
Detailed explanation-5: -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.
