Answers
pH is a figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid and higher values more alkaline.
Its important to know what is pH because we can differentiate what is base and an acid by measuring its pH and determine its strength(whether strong or weak)
In pH scale ,we have numbers from 1-14 where 7 is neutral and below 7 is acid and above 7 is a base
based on the colour of the pH paper we can determine the given compound as acid or base
pH scale =it ia a scale used to measure the acidity or basicity of a substance
Importance
