Exp 5 - Atomic Emission & Flame Tests

This is a FUN laboratory experiment doing qualitative flame tests for identification of a metal ions in aqueous solution of its ionic salt (today's solution: ionic salt as a solute dissolved in water as a solvent).

We want to work safely and quickly in this experiment following the directions and guidelines give these tutorials.

Here is a quick summary of the high lights of today's lab (Flame Tests),

  • Use a test tube rack to hold your test tubes, see image below.
  • Quickly label 9 test tubes and
  • Add 1 mL (fingered, eyeing this amount) of standard solutions listed on page 115 to the test tube.
  • Clean the nichrome wire as described in the Blackboard Assessment between burnings.
  • Burn each standard and control solution in the top part of the cone of the flame.
