Plan

Apparatus

The apparatus I will use to conduct the experiment are:

  • 1-clorobutane (1 mol)
  • 1-bromobutane (1 mol)
  • 1-idobutane (1mol)
  • Silver Nitrate (0.01 mol)
  • Ethanol
  • Water Bath (Heated to 50˚C
  • Test tubes x3
  • Test tube rack
  • Teat pipettes x3
  • Burettes (1mm³) x2
  • Pipette filler

Method

  • Set up test tubes and test tube rack
  • Put 1 cm³ of silver nitrate into the three test tubes using a burettes
  • Add ethanol(1cm³) with the other burette
  • Put test tubes in water bath (pre heated to 50˚C) and leave for 10 minutes test tubes will be placed in water bath at the exact same time

Safety

To make my experiment a safe one I will wear safety goggles (I also have done research into the chemicals I have using, this means I know what to do if I spill some upon my hand or on the floor) for example 1-iodobutane is a slight irritant

Fair Test

To make this as fair a test as possible I will use a water bath to control the temperature the bath will be heated to 50˚C I will place all the test tubes with the mixtures in the water bath at the same time, I will ensure that they have been in the water bath for ten minutes this should ensure that they are all at the same temperature as the temperature influences the rate of reaction it is essential I do this. I will use a burette to mesure the silver nitrate and ethanol this should ...
