The Plan
Variables: The variables for this practical are:
- The metal that it used- magnesium, copper or iron.
- The amount of metal that is used- any amount as long as it is divisible by 0.5 grams.
- 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.
