BlackburnRose Posted February 15, 2019 Share Posted February 15, 2019 Does anyone know what happens to Ferric Chloride if it freezes? Does the chemical compound change and it turn ineffective or is not and just fine to use after it thaws? I live in Alaska and sometimes we have to turn our house off when we leave and let it freeze, I don't want to be a burden to others by needing them to keep it while we are gone.

IronAlchemy Posted February 17, 2019 Share Posted February 17, 2019 Speaking as a chemist and not someone who has actually tested this, ferric chloride should freeze and thaw without damage. That said, you need to have it in a container that will not break when the liquid expands on freezing. The active etching from ferric chloride comes from hydrochloric acid released in the solution. It just does not maintain as high a concentration of acid as you can get with pure HCl. Quote Link to comment Share on other sites More sharing options...
