Question

What is the relationship between pH, acidity, and H1 concentration ?

Answer 1

pH = - log [concentration of H+]    

pH = - log [H+]

pH IS A MEAUSE OF ACIDITY AND BASIDITY OF A SUBSTANCE....

AS ACIDITY OF A SUBSTANCE DEPENDS ON THE IONISATION OF H+
THEREFORE IT IS A MEAUSE...

THE LOWER THE PH VALUE, THE MORE ACIDIC IS THE SUBSTANCE
