What happens when water gets too acidic?

Acidic water is water that contains a high concentration of hydrogen ions. pH is the parameter that is used to denote if a solution is acidic, basic or neutral. A pH of around 7 indicates a neutral solution, while a solution with a pH of less than 7 is known as an acidic solution.
If water gets too acidic, there are a number of concerns. If the pH of the water falls below 4, it can result in skin and eye irritation. At lower pH values, water becomes corrosive and may cause the leaching of metals such as iron, manganese, copper, lead, and zinc into water, thereby increasing the concentration of such toxic metals in the water. Acidic water may also taste metallic or sour, thus leading to aesthetic issues. If natural water bodies become too acidic, the animal and plant life within may be at risk, and reduced survival may be the result.
Hope this helps.
