WebpH 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. WebThe pH scale. How acidic or alkaline a substance is (the pH of the substance) can be measured using the pH scale, a continuous range that stretches from below 0 to above 14.
