First, take a clean wire loop of Platinum or nickel-
chromium . They may be cleaned by dipping in hydrochloric
or nitric acid, followed by rinsing with distilled or
deionized water.
Test the cleanliness of the loop by inserting it into a
bunsen burner flame. If a burst of color is produced, the
loop was not sufficiently clean.
Ideally, a separate loop is used for each sample to be
tested, but a loop may be carefully cleaned between tests.
The clean loop is dipped in either a powder or solution of
an ionic (metal) salt. The loop with sample is placed in
the clear or blue part of the flame and the resulting color
is observed.
In this way Flame test is done.
