A student has an unknown and does the following tests: 1. Flame test: result - lavender, light purple color 2. Solubility: result - no precipitate observed with any of the anions (carbonate, phosphate and sulfate) 3. Halide test: result - orange color in the upper layer. What is the full name of this compound? Write the formula. In the halide test what is the liquid in the upper layer? How would you write the formula of the molecular species in this layer?

At the point when a metal, metal particle or metal salt is added to a flame, an ignition response happens. This response energizes electrons in the metal from its ground state to a higher energy state. To get back to its ground level, the electron delivers the energy as light. Hence, flame tests are utilized to recognize the presence of metals or metal particles in a compound.
