This question is about chemical analysis.
An industrial chemist is analyzing a sample of a fungicide containing copper(II) bromide to confirm its chemical composition.
The sample is fully soluble in water.
Plan a method the chemist could use to show that the sample contains copper(II) ions and bromide ions.
The chemist has access to the following equipment and reagents:
You should describe the procedures and state the expected results for both tests.
The chemist could also use an instrumental method to identify the metal ions in the fungicide.
Identify the instrumental method that could be used to detect and measure the concentration of copper(II) ions in the sample.
State one advantage of using this instrumental method instead of a chemical flame test.
