The Plan Variables: The variables for this practical are: 1. The metal that it used- magnesium, copper or iron. 2. The amount of metal that is used- any amount as long as it is divisible by 0.5 grams. 3. The concentration of the solution of the solution- molarity 0.1M or 0.5M. I am going to change the amount of metal. Fair Test: To make this a fair test I must keep everything constant except the variable (the amount of metal). But even the variable must be changed at a consistent rate (going up in 0.5g). Method Apparatus List: * Copper Sulfate solution (0.5M). * Powdered magnesium (15g in total). * 2x Beaker. * Measuring cylinder. * Safety goggles. Measurements: I am going to use 50cm³ of copper sulfate and then us the following measurements of powdered magnesium 0.5g, 1.0g, 1.5g, 2.0g, and 2.5g. Safety: I will wear safety goggles throughout the experiment, I will be careful when I pour the solution and when I am...
