pH is the measure of H Ions Present in a solution indicating the acidic or basic strength of a solution. The pH of a Neutral Solution is 7. Values less than 7 on the pH Scale represent an acidic Solution whereas with the Increase in the Values from 7- 14 on the pH scale, the basic strength of the solution Increases. Our Body Works within the pH range of 7 - 7.8. pH of acid Range is 5.6. When the water from acid rain enters into rivers, it lowers the pH of the River Water which causes a lot of Da
