Question

You have a pond that has become too acidic, from acid rain, for survival of your fish. What kind of chemical could you add to the water to counteract that acidity?
Explain how this chemical would alter the PH.

Answer 1

If a base is added to an acidic solution, the solution becomes less acidic and moves toward the middle of the pH scale. This is called neutralizing the acid. You may add to your pond Na₂CO₃ or NaHCO₃.
