The Electro-Negativity of Atoms
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 50ËšC
* 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 50ËšC) 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 50ËšC 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 ensure accuracy in the volume. Human errors can affect the
results; I could use a micropipette array and a data logger to take
