The pH of a solution is a measure of its acidity or basicity. The pH scale ranges from 0 to 14, with 7 being neutral. A pH below 7 indicates an acidic solution, while a pH above 7 indicates a basic solution.The hydrogen ion concentration is a measure of the amount of hydrogen ions (H+) in a solution. The hydroxyl ion concentration is a measure of the amount of hydroxyl ions (OH-) in a solution.The pH of a solution is inversely related to the hydrogen ion concentration. The higher the hydrogen ion concentration, the lower the pH. The lower the hydrogen ion concentration, the higher the pH.In this case, the pH of the lake is 4.0. This means that the hydrogen ion concentration is 1 × 10-4 moles per liter of lake water. The hydroxyl ion concentration is 1 × 10-10 moles per liter of lake water.
