WebWhen an alkali metal is dissolved in hydrochloric acid and analyzed using a flame test, an intense orange flame is observed. Why might more information be needed to confirm the identity of the metal in the sample? A The orange color is difficult to differentiate from the color of the Bunsen flame. WebThe color-producing species are usually created from other chemicals during the reaction. Metal salts are commonly used; elemental metals are used rarely (e.g. copper for blue flames). The color of the flame is dependent on the metal cation; the anion of the salt has very little direct influence.
