Question 1
FA student uses flame tests to identify the metal ions in four solid compounds, W, X, Y and Z.
Figure: The apparatus a student uses to carry out a flame test on a solid compound
a.[2]
Describe how the student should carry out a flame test on solid compound W.
b.
[4]
Table shows the flame colour the student saw for each compound.
Table: The flame colour produced by each of four solid compounds
| Compound | Flame colour |
|---|---|
| W | crimson |
| X | yellow |
| Y | lilac |
| Z | green |
Name the metal in each compound. Use Table.
c.[2]
The student mixes compound W and compound X together and repeats the flame test. Only a yellow flame is seen. Explain why.
