P4 set fire to interrogatory for cations Flame interrogatory Introduction The brand coloration of gather 1, 2, and one Transition meeting metals. A number of thirdly estate metal ions (Li+, Na+, K+, Ca2+, Ba2+, Sr+, and Cu2+) ordinate a distinct color to a set fire to. Therefore, a blast experiment is oftentimes used as a confirmatory experiment in identifying an unknown metal. Apparatus Nichrome wire etna burner Solutions listed below in the table system The Bunsen burners flame should be good-for-naught and the golden (more often nichrome alloy) gyrate located on the be givenpytoe of the blue inside(a) cone shape of the flame. First, wash the loop dipping it into hydrochloric acid, rinsing with distilled water and checking the flame is no longer colored, so you are sure the test is not invalidated by any previous experiments. provoke some crystals of sample or dip it into the solution to be tested. Put the loop once again on the tip of the inner blue cone of the flame and observe.
