pH is a logarithmic scale. This means that for each one-digit change in pH, the acidity (H+ concentration) changes by 10 times.
For example, a solution with a pH of 4 has 10 times more H+ than a solution with a pH of 5.
A solution of pH 3 will have 100 times more H+ (it is 100 times more acidic) than a solution of pH 5.
For example, a solution with a pH of 4 has 10 times more H+ than a solution with a pH of 5.
A solution of pH 3 will have 100 times more H+ (it is 100 times more acidic) than a solution of pH 5.
