Flame Tests
A flame test is a qualitative test for some metal ions. A clean nichrome wire, dipped in concentrated HCl to clean it, then in the sample, is held in a roaring Bunsen flame. The colour is a clue, not a full proof if sodium yellow is also present.

Full school-level explanation
A flame test is a qualitative test for some metal ions. A clean nichrome wire, dipped in concentrated HCl to clean it, then in the sample, is held in a roaring Bunsen flame. The colour is a clue, not a full proof if sodium yellow is also present.
Remember
- metal ions
- nichrome wire
- flame colour
- clean wire
- sodium masks
- qualitative
- not how much
How the ideas connect
Clean the wire until it gives no colour of its own. A dirty wire that still has sodium will 'prove' every sample is sodium.
Deeper understanding
Go beyond memorising Flame Tests. Connect the definition to reasons, relationships, exceptions, and exam wording.
How the ideas connect
Clean the wire until it gives no colour of its own. A dirty wire that still has sodium will 'prove' every sample is sodium.
