Reaction between Boric acid and Calcium chloride
« on: July 02, 2020, 02:37:48 PM »
Hello!

I've read in the Wiley's guide of chemical incompatibilities that CaCl2 and H3BO3 are not compatible to each other. Unfortunately some kind of explanation is missing in the text. I am now just wondering why and which reaction between both can occcur?

I made some tests with dry powder mixtures before, and it seems when mixing some gas forms after 24 hours which leads to a positive color reaction of KI-starch paper.

Is it possible that both components form a Calcium borate type, releasing H2 and Cl2 which would be oxidizing?

Hope someone can help me to solve this riddle  ;)

Calciumchloride has a similar effect like Mannit, it will enhance the acidity pH will drop. But that it will develop oxidation compounds is not known.
