How acidic or basic a solution is. Simply, it's concentration of H+ molecules. The higher the pH value the lower the acidity.
pH = -log10[H+]
green indicates the pH value of 5-6 which is slightly acidic. for the whole pH color scale go to the reference cited.
The pH scale is the widely used universal scale, (which measures the hydrogen ion concentration of solutions) to measure the acidity or alkalinity of chemical solutions. It should be mentioned that the pH value is dependent on the temperature.
Typically, the pH scale runs from 0-14, but there is technically no limit to the pH scale. A pH of -25 (for instance) would mean the H3O+ concentration is somewhere in the neighborhood of 1025 (moles/L). Likewise, a pH of 25 would indicate an H3O+ concentration of about 10-25 (moles/L).
The highest number on the pH scale is 14. The pH scale goes from 0 to 14.
The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale

pH=7 is the neutral point on the scale.

Chemists devised a measurement system called the pH scale to indicate the concentration of hypotonic ions in solution. Therefore the higher the pH scale gets the more persistant it is.
