Is overcooling the haloform reaction even possible.

I believe both theory and experience would indicate that this isn't possible without extreme cold conditions.


I mixed 50 ml of acetone to a gallon of concentrated bleach found at the local Walmart.

The sodium hypochlorite was chilled to about 3 C via storage outdoors. The acetone was about 19C.

The solution turned white after acetone was added to it. I then quickly added ice. 19 hours later I went to decant and some ice was still present. The reaction container was stored at about 8-11 C when I went to decant.

I hypothesize that the bleach was not as concentrated as thought. The solution will react with choroform over time but it is said to be slow.

You added Ice in the reaction container? If so you diluted it further.
