  I don't think your explanation and the reaction given are true. First, any crosslinking would require a molecule with at least two functional groups, and ethanol has only one. Second, your reaction has oxygen as a product. Ask yourself - is really any gas produced? Keep in mind that the stoichiometry you've provided dictates that for each mole of ethanol reacting (ca. 50 ml) you'd get over 20 liters of oxygen. That's quite an off-gas, I'd say.

  Are you sure you are producing oxygen as a side product? To me it looks a bit sus that you are making Si-C bonds that easily. It looks more like Si-O-C, which would not produce oxygen gas, and is thermodynamically more favorable too.

  Sodium metasilicate (crystalline Na2SiO3) isn't usually sold to regular customers as it is because it's corrosive. If you bought your waterglass at a hardware store, it probably is an amorphous silicate variant much more rich in silica which is safer to handle. It is also good for making bouncy balls, though. When I was in middle school I used to make them all the time from silica-rich waterglass and denaturated alcohol. Now I wonder what happens if I use metasilicate.

  I did this in an oven, heating the calcium sulfite and sodium nitrate to 250C for an hour, packed down in the glass container and covered with 2 layers of foil to slow down the oxidation of my product. Once complete, I did the sulfuric acid test on the unprocesses product and it spontaneously produced the NO2 gas. However once I removed the sulfate/sulfite and recrystallized the product from water it doesnt pass the sulfuric acid test unless heated, implying its nitrate. My final product is a very slightly yellow crystalline powder, which could be nitrite but without evolving the NO2 from reaction with H2SO4 at room temperature I'm thinking its nitrate. Any suggestions as to why I passed the H2SO4 test before purifying the product, but not after?

  I may be stupid but how does sodium hydroxide dissolve silicon dioxide which is just glass?

• 
  @zenongranatnik8370Күн бұрын

  Strong alkalis just dissolve silicon dioxide creating silicates. Molten NaOH easily dissolves glass and concentrated NaOH solutions can dissolve regular sand under high pressure. If silica is in the form of silica gel it is even easier, you can easily dissolve silica gel cat litter in concentrated sodium hydroxide solution. It's an acid-base reaction, silicon dioxide is a very weak acidic oxide.

• 
  @eclectichoosier547418 сағат бұрын

  NurdRage covered the reaction in his sodium series. It's a common problem when working with NaOH, especially at higher temperatures. -- it likes to dissolve your glassware unless you completely eliminate water from your reaction. I've lost a few flasks to it. NurdRage starts his reactions by destroying ALL of the water with sodium metal.

  I just went down a bit of a rabbit hole on the subject of silicone's environmental impact. It's a mixed bag, but not an unmanageable one the way plastic is. It generally breaks down even slower than plastics (I'm sure there are exceptions due to how varied both can be), but that can be a positive for reusable items. It's terrible for disposable items, but ffs we gotta stop with that anyway. But at EOL, it can generally be incinerated safely, unlike plastic, since it mostly produces sand, carbon oxides and water, unlike all of the plasticizers and softeners and adjuncts added to make most plastics useful. Sure, produces carbon dioxide and monoxide, but compared to plastics... Not that it create much energy when incinerated, but the toxic outgassing is less. In a future without plastics, maybe we'd use more silicone and have a collection system for it so it goes into incinerators instead of landfills? Or maybe we'd find a recycling system that uses it as a relatively clean source of silica for glassmaking or more silicone?

  Near where I live there was an armaments works during WW1. A fire started in some empty sacks which ignited sacks full of TNT, which started an exponential burn which resulted in a detonation of a few hundred tonnes of TNT killing 108 people. So if you have enough TNT stacked together and set light to it then it can detonate. I'd guess that with a large enough mass the flame front accelerates into the mass until it goes supersonic.

  Neat, I didn't really understand silicone polymerization mechanism (not that I tried, but still).
