Describe briefly how you would carry out a preliminary investigation to find a suitable value to use for this variable? My variable is the amount of copper chloride. My hypothesis is : "The temperature rise when a metal reacts with a solution of copper chloride varies with the reactivity of the metal".
Can some one help me and tell me how i should answer this question? xx

1st and foremost, use 1 metal.
Otherwise: - place metal in CuCl2 solution (with measured volume) -place thermometer in the solution - control!!!! Time and concentration WILL affect your results
