ABSTRACT: Wnte a Claim/Evidence/Reasoning paragraph that answers the problem
question: "What is the identity of the unknown ion? Start with a claim sentence that
directly answers the question. Then provide specific data as evidence that supports your
claim as well as a summary of how you obtained that specific data. Finally, explain in detail
exactly how that evidence proves that your claim is correct. Please make sure that you
answer in complete sentences and in paragraph form.
The identity of the unknown ion is Lithium, Lit. Because, the flame color of an
unknown ion is pink Each element has its own characteristic emission spectrum.
From the given data, the only ion that gives a pink color on flame test is Lithium.
The principle behind flame test is - when the metal ion is heated, the atoms in it
absorb the energy and gets excited to higher energy levels and when they return
to the original level, emits energy in the form of visible light.
