How does lime help lower acid level in lakes?

Lime, primarily in the form of calcium carbonate (CaCO3), helps lower acid levels in lakes by neutralizing excess acidity. When lime is added to acidic waters, it reacts with hydrogen ions (H+) present in the water, effectively raising the pH and reducing acidity. This process increases the alkalinity of the lake, promoting a healthier aquatic ecosystem by supporting fish and other aquatic life that thrive in less acidic conditions. Additionally, lime can help restore the natural buffering capacity of the water.
