Define pH scale and explain.

1.	Define pH scale and explain.
Answer» pH scale: The pH of a solution is defined as the negative logarithm of hydrogen ion concentration in moles per litre. pH = - log [H⁺(aq)] The pH scale is a continuous scale and the value of pH varies between 0 to 14. The pH of pure or neutral water is 7. Solutions having pH less than 7 are acidic in nature and the solutions with pH more than 7 are basic in nature.

pH scale: The pH of a solution is defined as the negative logarithm of hydrogen ion concentration in moles per litre.

pH = - log [H⁺(aq)]

The pH scale is a continuous scale and the value of pH varies between 0 to 14.

The pH of pure or neutral water is 7. Solutions having pH less than 7 are acidic in nature and the solutions with pH more than 7 are basic in nature.
