A detailed Summary of Chemistry Lab

When comparing the results of the flame tests for solid sodium nitrate, solid sodium chloride and the sodium chloride solution, they all gave off the same colour. These results indicate that it does not matter which state the compound is in; it will still have the same properties. It also indicates that the wavelength was the same for sodium chloride and the sodium nitrate. Which means that it is the metal (sodium) that is responsible the new colour, not the non-metal (nitrate or chloride).

Potassium chloride and sodium chloride gave off similar colours - orange. They were hard to tell apart by viewing them with the naked eye, but because they are different metals it is known that the shade in colour (orange) would be slightly different. It looked as though sodium chloride gave off a slightly lighter orange - almost yellow. In this experiment cobalt glass was not used.

The chart of known flame colours (identification key) was completed because most compounds clearly produced different colours in the flame. However, some compounds such as potassium and calcium produced colours that (to the naked eye) seemed to be very similar. If an unknown substance was needed to be identified in this lab, it would have been possible to recognize it because of the Identification Key. The results from testing sodium chloride and sodium nitrate showed that the metal is responsible for creating the colour. This is because there was no difference in colour between the two compounds. Furthermore, the solid sodium chloride and sodium chloride solution test also proved that the state the compound is in does not matter, it will still produce the same colour. This is because there was no difference in colour between the two compounds.
