Question

I mixed baking soda and vinegar and after some time when the reaction stopped, I heated the solution. After some time vinegar evaporated fully leaving a blackish substance. Please explain the reaction.​

Answer 1

Answer:

When vinegar and baking soda are first mixed together, hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda. The result of this initial reaction is two new chemicals: carbonic acid and sodium acetate.
