Question

A sample has a hydrogen ion concentration of 1 × 10−2. What happens if the hydrogen ion concentration increases?

Answer 1

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+)
