Effects of Acidic Rainwater on Leaching of Sphalerite

Benjamin Allison

Hillary Stacey

I created an experiment that would test how much Lead (Pb) was leached if the pH of the water was decreased just like what is happening in the real world. I would purposefully change the pH and see how the amount of Pb leached was affected. This means that the pH of the water is the independent variable and the amount of Lead leached is the dependent variable. The amount of water, Sphalerite, and temperature are to be held constant.

One thought on “Effects of Acidic Rainwater on Leaching of Sphalerite

  1. Excellent work!!! I like the real-world problem-solving approach, display of enough evidence of each step during the experiment.
