Which 2 metals and liquid combination can produce the most electricity? We believe that this will be the combination of copper and zinc mixed with vinegar. We found that copper and zinc mixed with salt and water conducts the most electricity. This shows us that our hypothesis was partially correct. We guessed the metals correctly but the liquid solution we guessed incorrectly. Some of the factors that may have affected our results are inexact measurements in the solutions, unmixed solutions, and faulty readings on amp meter. However we have tried to minimize the amount of errors by doing the experiment over and over and took the averages of the results. Our hypothesis was wrong. I feel that we have gone through most of the factors that could have swayed the results and fixed them. The solution of salt and water with copper and zinc made more electricity than a new AA battery; this could be effective in the real world if we could figure out a way to power appliances with this solution. If we did this it would be more effective than what we use now.
