Flame Tests for Metal Ions | GCSE Chemistry
Flame tests are used to identify metal ions (cations) based on the distinctive colors they produce when heated.
What color does Potassium produce in a flame?
What is Flame Tests for Metal Ions | GCSE Chemistry?
"An analytical procedure used in chemistry to detect the presence of certain elements, primarily metal ions."
What color flame does a Sodium (Na+) ion produce?
A student sees a lilac flame during a test. Which ion is present?
Why can a flame test be unreliable if the sample is a mixture of ions?
