Question

I would like to know which branch or area of chemistry is appropriate for bath bomb? It is a combination of baking soda (sodium bicarbonate) and citric acid that is when dissolved in water, creates fizz. I'm not sure if it's organic chemistry (medicinal chemistry) or physical chemistry (chemical kinetics).

Please help.

Answer 1

The bomb for the bath belongs to organic chemistry, because the citric acid is an organic compound. And the formation of foam, which occurs when the bomb dissolves in water, belongs to colloidal chemistry.
