Enthalpy changes on displacement and the reactivity series.

Extracts from this document...


Enthalpy changes on displacement and the reactivity series Introducton In this investigation my task is to design a plan for an experiment involving enthalpy change of a displacement reaction between a metal and a solution of a displacement reaction between a metal and a solution of salt is related to the relative position of the two metals in the reactivity series. I will be provided with zinc metal and solution of copper sulphate and lead nitrate. Procedure I will firstly measure out copper sulphate solution and giving the concentration as molarity. I then in turn weigh out the zinc, I will do this my putting it in a weighing bottle and then put the weighing bottle on a balance. ...read more.


I will repeat the experiment again except this time I will use lead nitrate solution instead of copper sulphate. I will then use the formulae M*C* T To find the enthalpy change. ( I will go to the formulae later on in the plan). Apparatus I will use the following apparatus in the experiment: * Beaker * Measuring cylinder * Thermometer 0-100 * Balance * Weighing bottle * Goggles * Burette Amount of substance I will use 150 cm of copper sulphate solution. I will the use the following formulae to calculate the moles of copper sulphate which is: Volume * concentration = 100*1 = 0.1 1000 1000 I will measure the volume of copper sulphate. I am also going to calculate the mass of zinc by using the following equation: Moles of zinc = Mass. ...read more.


Iw ill then convert my results in to kilo joules by dividing them by 1000, which then I will divide by the moles of copper sulphate or lead nitrate. Safety In this experiment I will need to use goggles to protect my eyes from any of the solution splashing out. Will also need to wear gloves because lead is poisonous and because the copper sulphate can be corrosive. Accuracy of results To ensure that my results are as accurate as possible I will repeat the experiment a number of times. I will also look at the measuring temperature more carefully so the readings are correct. I will use a bomb calorimeter instead of a beaker because it's a much better insulter meaning less heat will be loss to the surroundings, and so my results will be much more accurate. ...read more.
