When you add wine into banana flambe while being heated, pink or almost fuchsia colored flame is produced.Why?

Question

So, what's in the wine..

Answer 1

Electrons in the potassium chloride are being excited to higher energy levels, because they are absorbing thermal energy, due to the fire. The energy they absorb to go up one energy level is expressed as follows:

E = nhf

When they go DOWN an energy level, they lose a specific amount of energy, equal to hf, and that energy is emitted as a light. This causes the flame to become a different color. For instance, if you put barium chloride in fire, it will become green.

So to answer your question again, when the electrons lose energy, they emit it in a form of electromagnetic radiation with a wavelength that allows it to be visible light.

Alcohol is a known solvent. Although wine has little alcohol compared to other beverages, that alcohol dissolves some potassium from the banana. The potassium then somehow reacts with a chloride anion to form potassium chloride. Potassium chloride is known for making fire purple. I just looked up the color fuschia online, and I found out that it's kind of like purple. This confirms my answer.

Answer 2
