Lab 7: The Flame Test (Ions)

October 22, 2008 The Flame Test Julie Anne Aguilar, Prd 1.4

Purpose: To observe the colours of some ions if they were burnt.

Materials:
-Element Ions
-Saturated Splints
-Bunsen Burner

Procedure:
1. Burn the saturated splint.

Data and Observations:
Strontium (Sr) Ion
Colour: Red
Accepted Flame Test Colour: Red

Calcium (Ca) Ion
Colour: Pink or Scarlet Red
Accepted Flame Test Colour: Yellow/Red

Barium (Ba) Ion
Colour: Yellow
Accepted Flame Test Colour: Yellow

Lithium (Li) Ion
Colour: Purple/Lilac
Accepted Flame Test Colour: Scarlet Red

Copper (Cu) Ion
Colour: Green
Accepted Flame Test Colour: Green/Blue

Sodium (Na) Ion
Colour: Bright Orange
Accepted Flame Test Colour: Bright Orange

Potassium (K) Ion
Colour: Orange
Accepted Flame Test Colour: Lilac

Conclusion:
I think some of my colour observations were wrong because when we were observing it, the splint started to burn. Therefore, if the splint started to burn, we were not observing the flame produced by the ion but we were observing the flame produced by the splint.
