Question

If pH stands for "percent of Hydrogen," why is there 'more' Hydrogen ions contained in a substance with a 'lower' pH? It seems logical that the pH scale (ranging 0-14) should increase in amount/percent of Hydrogen ions as the numerical pH value increases.
This question is just for trivial knowledge.

Answer 1

H+ ion concentration is more for strong acid.More hydrogen atoms are present in more H+ concentration

PH = 1-----------------3 ---------------------------7 -------------------------10-------------------------------14

            strong acid      weak acid         neutal    weak base       strong base

percentage of H+ ion increases dilution of acid is increases.When dilution is increases PH value is increases.

example [H+] =10^-1 for strong acid. it contains more number of H+ ions But PH =1 is lower.

             [H+] = 10^-5 for dilute acid or more percentage of acid. But PH= 5 is more
