Detailed explanation-1: -The scale has values ranging from zero (the most acidic) to 14 (the most basic). 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. Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic.
Detailed explanation-2: -In a chemistry lab, you determine how acidic or basic something is by using the pH scale. The scale ranges from 0 to 14 with 7 considered neutral, as is the case with plain water. Anything below a pH of 7 is an acid, and anything above 7 is a base, or alkaline.
Detailed explanation-3: -pH is an expression of hydrogen ion concentration in water. Specifically, pH is the negative logarithm of hydrogen ion (H+) concentration (mol/L) in an aqueous solution: pH =-log10(H+) The term is used to indicate basicity or acidity of a solution on a scale of 0 to 14, with pH 7 being neutral.
