Topic 1.2 Flame Tests

What is the qualitiative test used to identify metal ions when you take a nichrome wire loop with an unknown compound into a flame and observing the colour?

• Nichrome test

• Filament test

• Flame Test

• Flamability test

What is the first step of carrying out a flame test to identify metal ions?

• A metal loop is dipped int the sample

• The clean metal loop is dipped into hydrochloric acid

• The metal loop is placed directly into a bunsen burner blue flame.

• The metal loop placed in the blue flame is observed and the colour recorded.
