Qualitative Analysis Test
Write up for Qualitative Analysis 1.
Introduction- This experiment is for qualitative analysis so we are trying to find out what is in a substance. In this case we are using the flame test to try and discover what is in 4 unknown sample solutions that we have been given this is done by cross referencing the colour of the flame with 6 known solutions we test beforehand.
Aim- In this experiment we are attempting to distinguish what substances are in the 4 unknown solutions by cross referencing with the 6 known solutions we test beforehand.
Assumption- Not applicable for this experiment as we would have no clue as to what each unknown solution was.
Risk Assessment- Material used/procedure- * The Flame Test * Gloves * safety glasses * lab coats * Bunsen burners * wire hoop * 4 …show more content…
Then lab coats, safety glasses and Gloves were equipped to ensure that safety hazards were avoided as much as possible. The Bunsen burners were then lit and put onto the safety flame. The equipment was then sterilised by dipping it into the Hydrochloric acid, and turning the Bunsen onto a roaring flame it was placed in the middle small triangle (the hottest part of the flame) and this step was repeated 5 times to get a reliable control flame colour. The hoop was dipped into one of the known solutions and placed in the hottest part of the flame. A short lived coloured flame was visible and this colour was recorded. After this the hoop was then sterilised in the hydrochloric acid again until the flame was the same colour as the control flame. This process was repeated until all 6 known solutions had been tested. Then the 4 unknown sample solutions were then tested in the exact same way, and recorded. Comparisons were then made by cross referencing the colours from known and unknown
