Question

what caused the color? the flame was pink/purple for the green bear just like the red bear. therefore, the color of the gummy bear did not affect the color of the flame. instead, the color of the flame was due to the chlorine in the potassium chloride. this was similar to the flame test lab where we discovered that the were what caused color changes in the flames.

Explanation:

In flame tests, the color of the flame is determined by the metal ions present in the compound. For example, potassium ions (from potassium chloride) produce a characteristic flame color (like pink/purple here). Non - metals generally do not produce distinct flame colors in the same way as metals do. So the species that cause color changes in flames during flame tests are metals.

Answer:

metals
