Flame Test

Extracts from this document...


Flame Test Aim My aim for this experiment was to test and investigate the different salts that I was given. I was given 5 different salts and they were labelled as the following: a b c d and e. I had to find out the colour of the flame when the salt is heated in the Bunsen burner flame. Apparatus These pieces of equipment will be needed to carry out the experiment. * Bunsen Burner * Hydrochloric acid * Inoculating loop * Five different salts. Method * Place the inoculating loop in the Bunsen Burner to sterilise the loop. Then place the loop in the hydrochloric acid and then place in the flame. ...read more.


Symbol A Brick red Calcium Ca B Bluish green Copper Cu C Intense Red Lithium Li D Lilac Potassium K E Golden yellow Sodium Na Evaluation When burning the sample in the flame the colour of the flame wasn't clear. I overcame this problem by using more of the salt until the colour was clear. Also when going from one test to another the tests was contaminated and there was a mixture of colours. I overcame this problem by placing it in the flame then placing it in the hydrochloric acid then placing it in the flame. I did this until I saw that when I place the loop in the flame that there is no colour. ...read more.


In the hospital the process is done in an ionisation chamber. First a pipe is run to the flame, were a urine sample will be pumped into the fire. This is done to find the type of salt in the sample and also to calculate the concentration. A light beam is passed through the fire and then into a computer. A lens is put between the fire and the computer so that the beam of light is focused. The computer will have a data base on all the different metals. The way each metal is identified is by the wavelength pattern of the light. The sample of light is then run through the data base and then a match will be found. ?? ?? ?? ??
