The pH scale represents the relative concentration of hydrogen ions in a solution.
The concentration of hydrogen ions is commonly expressed in terms of the pH scale. Low pH corresponds to high hydrogen ion concentration and vice versa. A substance that when added to water increases the concentration of hydrogen ions (lowers the pH) is called an acid. A substance that reduces the concentration of hydrogen ions(raises the pH) is called a base. Finally some substances enable solutions to resist pH changes when an acid or base is added. Such substances are called buffers. Buffers are very important in helping organisms maintain a relatively constant pH.
The pH scale is a scientific classification of how acidic or basic a substance is. The scale ranges form 0 to 14 -- a pH reading of 7 is neutral in nature , a pH less than 7 is acidic in nature and a pH greater than 7 is basic in nature.

Watermelon has a pH of around 5.18 to 5.6. See Related Links.
A solution which has a pH lower than 7 is a acid.
It`s called acid(such as HCl,,,,PH=1)
Purified water should have a pH level of 7. The values of 7 is neutral on the pH scale.

The highest number on the pH scale is 14. The pH scale goes from 0 to 14.
