zinc and cuso4 reaction
An Investigation Into The Factors That Affect The Enthalpy Change During A Displacement Reaction.
Background Knowledge
The reactivity series is an order that places metals in that series depending how vigorously that metal reacts with water, air or acid. A more reactive metal could displace a less reactive metal from its' compound.
Zinc (Zn) is a more reactive metal than Copper (Cu); it is higher in the reactivity than copper and thus when some zinc is placed in a solution of copper sulphate a displacement reaction takes place. The zinc goes into solution while the copper is "forced" out of solution. The situation can be described as follows:
The full equation is: Zinc + Copper Sulphate = Copper + Zinc Sulphate
Zn(s) + CuSo4 (aq) = Cu(s) + ZnSo4 (aq)
The Ionic equation is: Zinc + Copper = Copper + Zinc
Zn(s) + Cu 2+(aq) = Cu(s) + Zn 2+(aq)
The experiment will be exothermic; this means during the reaction, energy will be given off, mainly heat energy.
The specific heat capacity (Shc) of a substance is the amount of heat needed to raise the temperature of one kilogram of it by one degree Celsius.
