Is the light produced in a flame test from a physical or chemical change? Explain your answer.
Answers
Answer:
Chemical reactions are really physical reactions at the atomic level. We have given them a unique name so chemists would have employment, but they are really physical reactions. At that level there is no distinction.
The metal ions in a flame test are wafted away by air currents associated with the flame. They do not ‘disappear’ but react with airborne elements - often oxygen - and become ‘dust’.
