I use calcium chloride to adjust water for brewing beer.
Thank you. Okay but what is it exactly? Is it salt? Is it calcium? Is it calcium salt? What is it? And what chemical reaction does it contribute to your beer brewing?
Yep, it’s a salt. @themeatbridge explained it really well.
In brewing, it’s really important to have calcium in the mash, where you’re converting starches into sugars. It helps maintain an optimal pH and the enzymes that do the work need it as well. It’s also important for yeast health. Chloride accentuates malt flavour in beer. I’ll add more or less depending on the beer style; more for a stout, for example, and less for an IPA. I’ll add more gypsum (calcium sulfate) for more hoppy styles because sulfate imparts a dryness than accentuates hops.
Fun fact: You can’t store calcium chloride in powder form if you need precise amounts of it because it’ll absorb moisture from the air over time. The first time I used it, I mixed it with water in a glass bottle I was holding not realizing that it’s incredibly exothermic. It suddenly got blistering hot and was steaming like crazy. Burnt my hand and scared the shit out of me!
What no German Purity law adherance? /s
calcium chloride – CaCl2 – primarily road de-icing
not sure why you crossed of “2” there? the formula in the wiki page does have 2 for calcium chloride.edit 1: but, apparently there does exist calcium monochloride
edit 2: crossed off comment, apparently my app shows the “2” being crossed off, but it’s technically a subscript.
Seems to be a problem with your client/frontend. It’s not crossed of, it’s a subscript.
yes, you’re right. that’s a bit odd.
Calcium has 2 valence electrons, so you’ll need 2 Clor atoms to make it stable.
Calcium chloride exists, it’s CaCl₂. You need two chloride anions for each calcium cation. [see note*]
It’s safe to eat as long as food grade. In fact it’s used in cheesemaking. It’s salty and bitter. It’s also used to dehydrate stuff in laboratory, since it absorbs water like there’s no tomorrow.
It doesn’t behave like metallic calcium at all. Just like sodium chloride (aka table salt) doesn’t behave like metallic sodium (warning: loud noise).
*Note: technically CaCl (one chlorine) exists, as a diatomic molecule. Rarely found in stars, you won’t find it in Earth.
