Planning In this investigation I am going to investigate the various heat released during a displacement reaction when one factor, the variable, is changed. There are a number of variables which could be used in this experiment. You can change the metal used, the concentration of the metal salt, the amount of the metal, the type of metal salt, or the volume of the solution. In the experiment, the independent variable will be the concentration …showed first 75 words of 1484 total…

…showed last 75 words of 1484 total…A further problem was the accuracy of the measurement of the metal salt and distilled water. This could be improved by using a more accurate measuring cylinder, and again, aim for perfection. To extend the experiment, you could try to use more of the metal but continue to look at the concentration. You could then try another amount of the metal and then try to make conclusions by putting three different lines on one graph.
