“The heat is dissolution” would be an amazing album

What keeps our stomach acid from reacting this way?

The ‘Heat of Dissolution’ sounds like a Living Colour song title.

"The Heat of Dessolution" Best metal Band name you can pick.

Kamw :
It only happens with strong acids so something like glacial acetic acid wouldn't really warm up at all, also strong, concentrated acids like HCl generate some heat but not as extreme as sulphuric acid. So it's just really important to be careful with mixing strong acids, bases and anhydrous but very hydroscopic salts with water

Question: when I worked in the lab, I swore that ACN + Water got colder. Am I losing it?

Exothermic reaction. Chemistry teacher did this demo for us in the 90s

you dont have to get into the specifics of heat of dissolution and all that, the main point is that if there is a splash, it's going to be the stuff already in the container

"Never give acid to drink" my Chemistry teacher told me😁

After 40 years I realise what 'exothermic reaction' means.

I was always told it had to do with splashing. If your mixture splashes, you’d rather it be most water than mostly acid.

As a lab tech, I always explain to the new ppl why we have dos and don'ts. And when possible, give personal examples (see this lil hole in my lab coat? Yeah that's from this diluted acid so now you know to be careful and wear PPE). That's how we have the best chance they they'll actually listen and remember the rules/tips/advice. Same with explaining how/why protocols work. We can't just follow stuff without knowing why and call ourselves scientists!

if you pour salt into water it boil quicker

RavinAmulet :
the one exception I've always been told is when you are adding to a narrow necked vessel such as a volumetric flask, you do it the opposite way so that if there's steam generated, the water is forced back out instead of the acid.

iggyferret :
but also some get cold! for example sodium nitrate. and I think those cold packs that you squeeze to activate are usually sodium acetate?

NaCl and water is endothermic

But also if you add water to some salts it actually gets colder! Thermochemistry is wild.

doesn't this happen too when adding a strong base to water then ?
