Main Use for pH Paper

Let me give a brief about pH scale first-

pH scale is a scale to measure the acidity and basicity of a liquid. It has readings from 1-14 where 1 shows the most acidic substance and appears the most reddish in colour and 14 shows the most basic substance and appears the most bluish in colour. 7 pH is for neutral substances that are neither acidic nor basic and gives greenish colour.

Now, pH plays a very important role in our lives. It is used in several applications. For example, a swimming pool must be constantly maintained by checking its pH. If the water becomes too acidic or too basic, acidic or basic chemicals must be added to the water to balance out the number of H+ ions and OH- ions.
