pH works on a (negative) log scale, which means for every 1 point the pH changes, the H ion concentration changes by a factor of 10. So when the pH drops by 1.0, the H+ concentration increases 10 times. pH=-log[H+] (where [H+] is the concentration of H+)

When PH level decreases by 1.0 that means it becomes 10X less acidic (1/10 the concentration of H+ ions as before).

the lower the pH the higher concentration of hydrogen ions
