Making Very Shitty Silica Gel From Sand (and making disodium silicate)

[@philouzlouis2042]

Silicic acid, Na silicate... Nice. You are now ready for some DIY catalyst deposition, for some column chromatography packing... or for colorful chemical garden...

[@ecv80]

I liked your approach of just pouring HCl over not knowing the amount of the other compound. It's just pragmatic. No need to break your head over things like that.

[@THYZOID]

Might do some Grignards this week after finding easy ways to dry the reagents.

I remember the old KZbin channel ChemPlayer. You show the same expertise.

@@jfcrow1 Why was Chemplayer's channel terminated?

@@oitthegroit1297 Even though they explicitly stated they will never do explosives or drugs I believe one of their experiments did indirectly purify a derivative of meth from a commercial drug (KZbin was trying their best to get them deplatformed). They got three strikes, had enough and went to bitchute but only lasted a few months there. Do not know what happened to them since. But oh where they great chemists. I saved all their videos.

hhahaha well at least you tried. nicely done. if you ever want to revisit this in the future: 1) in a teflon container, heat both glass shards and NaOH with water. (nurd rage used a glass container but idk about that one chief) 2) the resulting solution should be added to 300 mL or so of waterwater at a rate of approx 1-10 mL /min, with an addition funnel and strong stirring 3) at the same time, add HCl and try to keep pH at 8-10 - this requires some trial and error - during the whole addition. I used sulfuric acid, 96%, and my ratio was approx 1 mL sulfuric acid to 12 mL of Waterglass (composition approx 30% w/w SiO2, 8% Na2O) 4) at the end of the addition of all silica gel, that is, however much you want to add, neutralize to pH 4 keep in mind that hot pH will be further away from neutral than cold pH! (if the solution is basic, it will be more basic, if it's acidic, it will be more acidic)

I think using sand was for fun and just for sake of the video

[@edoardobandieri2688]

In water it works even better! Try using silica based cat litter

[@ThorirLenvik]

If I'd done it, I think I'd started with crushed glass. You could have removed more iron or manganese, easily. You can also get a solution of silicate ("water glass"), and just done the precipitation. Making a silica for chromatography or drying, is more of a challenge. You can also isolate silica from many different plants and herbs. Just a comment. You have done a good demonstration by making the glass, from sand and soda! I loved to seed a solution of the silicate with crystals of various transition metal salts. It looks like growing seaweeds with many different colours !

What is the point of making SiO2 from NaSiO3, when you used SiO2 to make the NaSiO3?

[@dansw0rkshop]

Crystalline vs non-crystalline. Silica gel is non-crystalline and has a variety of uses that sand won't do. They're both SiO2.

Huh, reminds me a bit at NURDRAGE 😭 I miss him 💙❤️💙 I hope he's well! Nice way to get Silica....😎

[@JustinKoenigSilica]

yes nurdrage made the waterglass a long time ago kzbin.info/www/bejne/rp3Xp6qepMyeoqs

[@yasserotb1454]

If you want to, try to heat up titanium metal and put it in liquid chlorine The reaction is beautiful

[@SodiumInteresting]

Nice one

[@SuperAngelofglory]

@0:49 - plus you really don't want molten NaOH in contact with Al

[@THYZOID]

this is steel not Al

[@SuperAngelofglory]

@@THYZOID I know, but you mentioned why you didn't use Al

[@science_and_anonymous]

I say make pure chromatography silica and run a column.

[@mattbanks3517]

Add more naoh, get it to melt

[@WabuhWabuh]

i thought they just let crushed quartz grind until a certain size in a roller

[@karolus28]

cool
