Dip the platinum wire into a test tube of
concentrated hydrochloric acid and then heat
it in the hottest part of the Bunsen flame until
no characteristic colour is shown.
After the cleaning, dip the wire into the
concentrated hydrochloric acid again and then
into the white solid.
Heat the solid sample on the wire in the
hottest part of the non-luminous flame.
Observe and record the colour of the flame.

The platinum wire was dipped into a test
tube of concentrated hydrochloric acid and
then heated in the hottest part of the
Bunsen flame until no characteristic colour
was shown.
After the cleaning, the wire was dipped into
the concentrated hydrochloric acid again and
then into the white solid.
The solid sample on the wire was heated in
the hottest part of the non-luminous flame.
The colour of the flame was observed and
recorded.
