Acids and Bases are measured by the pH scale, which measures the concentration of H+ ions in the solution.
The lower the value on the pH scale, the more acidic the solution is and the more H+ ions there are in the solution.
The higher the value on the pH scale, the more basic or alkaline the solution is and the less H+ ions there are in the solution.
The pH Scale is Logarithmic
The pH Scale is Logarithmic
Each step on the pH scale is a change by a power of 10.
Since it is a negative logarithm, the larger the number on the pH scale, the more negative the exponent will be, and the lower the concentration of H+ ions will be
For example, if the pH of a solution changes from 3 to 1, it increased its hydrogen/hydronium ion concentration by 100x.
It went down on the pH scale, and lower numbers are more acidic (and acids donate H+ ions), so that is why the H+ ion concentration increased. It went from 3 to 1, a difference of 2 steps on the pH scale. Since each step on the pH scale is a 10x difference in H+ concentration, two steps is a difference of 10 x 10, which is a 100x difference.
