Identification of ions by chemical and spectroscopic means
Question
- A. Crimson
- B. Yellow
- C. Lilac
- D. Green
Answer
The correct answer is Green. It matches flame test because the evidence is flame colour and the expected result is metal ion identity.
Explanation
The correct option is Green. The answer stays inside Identification of ions by chemical and spectroscopic means by linking the observation to the conclusion instead of naming a substance without evidence. Other options are weaker when they confuse gas tests, flame colours, ion-test precipitates, chromatography evidence, or pure-substance/formulation wording.
Common mistake
Copper Flame Test Mistake
Students often confuse the flame color of copper ions with that of other metal ions, incorrectly identifying it as blue instead of green.
Remember that copper ions specifically produce a green flame during the flame test. Practice observing the flame colors to reinforce this identification.
