Question

what is ph value.......??we need to learn or we have to find​

Answer 1

a scale for measuring hydrogen ion concentration in a solution called pH scale has been developed the P in pH stands for portents in German meaning power....

on the pH we have measure pH from 0 ( very acidic) to 14 ( very alkaline) VH should be thought of simple as a number which indicates the acidic or basic nature of a solution higher the hydronium Ion concentration lower in the pH value the pH of a neutral solution is 7 values less than 7 on the pH scale represent an acidic solution as the pH value increases from 7 to 14 it represents and increase in OH- Ion concentration in the solution that is increase in the strength of alkali generally paper impregnated... with the universal indicator is used for measuring PH

hope this helps you....
