@Sam Hey Sam

@Sam It's most definitely a mixture of different salts

I dunno what knowing its composition would achieve for you.

If it's an assignment, then they probably already know what they dissolved, and you have to figure it out with some reaction.

Depending on what you have available, you could use strong acids or bases, some redox reactions etc. to figure out what the salt is, but I think it should then need more than 'household' safety

To find out a composition quantitatively, you often need enough of a strong reaction that would produce an observably significant result. So you need to know it's not gonna release some toxic gas, or react vigorously and throw boiling water at your face

Although what salt does that, hmm

@1,3-feeds They're called scrapers, welcome to the scrapers of the bottom of the digital industry

@pentavalentcarbon I dunno, I kinda like the rusty vintage post-apocalyptic visage

@Martin-マーチン hi, you're talking to one. How may I help you

@Ortho! How goes it?

@FadedGiant Yes, is there a way to differentiate them? — ygy 15 mins ago

I don't get it.

Okay, lets fixate on NaCl

Is there any way I can extract the molecules with household appliances?

I have a filter, a stove and test water

And a pan

I tried just heating it up but the residue will stick to the pan and I can't get it off

Q: How does iceskating work?

I was willing to understand a little bit better the physics behind iceskating. Messy thoughts From New Scientist (1964) (probably not the most up-to-date reference $\ddot \smile$), I found a diagram showing the relationship between both the static and kinetic coefficients of friction and the te...

@Sam Extract the molecules? Didn't you just evaporate or distill it?

Q: Can silicon dioxide melt at 20 °C?

Can $\ce{SiO2}$ melt at $\pu{20 ^\circ C}$? I have searched the web for $\ce{SiO2}$ phase diagram, but it seems to me that almost all the graph I can find have the temperature axis where the minimum temperature is in the hundreds degrees Celsius. Is it theoretically possible that with an high ...
