Wasn't even told that about those things in HS chemistry in my time in my country, not sure why - considered too dangerous knowledge by educators? Only found out about it on 4chan and gasped on how easily we could have accidentally injured ourselves while cleaning our dorm bathroom.

I learned about these from the book "A Child Called It". When the abusive parent uses the bleach+ammonia mixture on him. Then I tried to figure out what else bleach could do. This is not a healthy line of experimenting for a dumb 17 year old. I 100% believe HS chem should teach this. Then at least you know what not to do.

  Isn't it very clearly printed on the bottle in your country? Here (I assume this is an EU regulation) it says "WARNING! Do not use together with other products. May release dangerous gases (chlorine)."

    Here's a couple of typical labels in the US: https://i5.walmartimages.com/asr/2025dfde-c877-4043-b91d-9784760eba8f_1.e4371637d2a5cbd2e86ded8dd722ffce.jpeg?odnWidth=undefined&odnHeight=undefined&odnBg=ffffff https://i5.walmartimages.com/asr/2025dfde-c877-4043-b91d-978... https://i5.walmartimages.com/asr/05122787-1991-4084-869e-755630b006fb_2.df5e0c8f14c7476c647f0ffe987f2942.jpeg?odnWidth=undefined&odnHeight=undefined&odnBg=ffffff https://i5.walmartimages.com/asr/05122787-1991-4084-869e-755...

      The "DO NOT use or mix with other household chemicals, such as..." part should probably go on the front and a little bigger. I can't imagine that everyone would read the whole thing.

        It's okay, because they pointed out that it's a violation of federal law to use the product in a way inconsistent with the labeling. Checkmate people who don't read the label.

      Here's an EU (UK/Ireland so it's English) one: https://images-na.ssl-images-amazon.com/images/I/81nqrPdi1nL.jpg https://images-na.ssl-images-amazon.com/images/I/81nqrPdi1nL... There are almost 200 pages of EU rules and guidance in the first document [bottom of 1], and some hundreds more pages in related sections of that site. That said, the cheap-brand bleach in my cupboard has a word-for-word translation into Danish of the English text, and a consistent layout, and there's some merit in that.

  Wow, I wasn't sure if it was just me! Coincidentally that was also the same book I learned about those two being dangerous mixed together. Just curious, have you read "Go ask Alice"?

I really don't know how any chemistry can be taught without teaching metal + base reactions, or without teaching salt + acid reactions. I really really don't think your educators missed the rules that make it possible to know what happens when you mix foil with pipe cleaner or bleach with vinegar, they might've just not mentioned the very specific reactions and you failed to generalize.

I learned about it through The Anarchist Cookbook. They don't teach you in high school not to transport gasoline in a styrofoam container.

  They don't teach you how organic solvents often dissolve polar materials such as various polymers? I'm really becoming befuddled here, what do they teach then?

    Well, my grade school science teacher was also my gym teacher (he may have held a third position). So we mostly just sang periodic table rhymes and made baking soda volcanos. Despite what you may have heard, the average middle-American education doesn't prepare you for the hard science of the real world.

      Illuminating, I didn't know it was that inconsistent. I have a newfound appreciation of my own teachers now.

One has to ponder if starting teching that will result in the next TikTok bleach+vinegar inhalation challenge.
