acid precipitation inhibits the growth of Elodea, a possible experiment would be to place some
plants in water with a neutral pH and some in water with an acidic pH. each day, the growth of
each plant would be collected. if the plants in the acidic water showed less growth compared to
the plants in normal water, the hypothesis would be supported
