Methods of Identifying Ions
1. This question has 3 part(s).
1.1. A student had a solution of an unknown compound, Y.
They performed the following tests on fresh samples of the solution and recorded their observations:
Test 1: | Add sodium hydroxide solution |
Observation: | Green precipitate formed |
Test 2: | Add dilute nitric acid followed by silver nitrate solution |
Observation: | Yellow precipitate formed |
The student concluded that the formula of compound Y was FeI3,
Is the student's conclusion correct?
Explain your answer.
1.2. The student repeated Test 1 on a solution of another compound, Z.
A white precipitate formed.
The student concluded that magnesium ions were present.
Explain why the student cannot make that conclusion based on the test results.
Give details of how they could use other tests to identify the metal ion present in compound Z.
1.3. The student wanted to further identify compound Z.
They added dilute nitric acid followed by silver nitrate solution.
Explain how the observation of a cream precipitate helps confirm the presence of bromide ions in compound Z
