You are describing recrystalization. The obtained crystals (if any) may have a different phase than the initial solid (crystal or not) and can also have a cocrystallized solvent.

Tin(ii) is harder to reduce than Cu(ii) and Ag(i). Oxalic acid / oxalates may be a suitable alternative to ascorbic acid. While a weaker reducing agent in terms of standard potential (if memory serve), the release of CO2 may drive the reaction by displacing any equilibrium, especially if heated.

It sounds like your problem isnt electrochemical but simply chemical. You are generating chlorine which is the precursor to your target product. How is the pH? Chlorate forms from chorite under warm alkaline conditions.

Are you refining silver for purposes other than exploring science? Silver, unlikely gold, is actually fairly cheap and refining silver, even from scrap, does not offset the costs of whatever chemicals and tools you will need to achieve that. That said, if you are doing it for fun, why are you...

If you have a sufficiently advanced civilization, then a projectile with an antimatter and matter compartment that combines upon impact.

How are you identifying chlorine gas? For the record, producing 'lots of chlorine gas' is a serious safety hazard in itself! Anyhow, by smell, slight yellowing of the brine? I am no expert, but the chemistry suggests your reaction may be too cold. Chlorate is supposedly formed from...

Children's clothes should have a "This way front" type print similar to how claymores have "Front towards enemy".

Very good example and I vaguely recollect a video demonstrating this. Something along the lines of e coli (or another bacteria) on a surface of antibiotics, and the evolved species would traverse the entire surface.

Our interpretations of stories are interesting, because we will ascribe meaning to narratives as being metaphors, allegories or allusions, yet our lived experiences are always interpreted literally. No one ever thinks "My back pain is a metaphor the burdens I bear ". They just think "I should...

I impressed your mother carried you to your As someone from the upper middle class (arguably only recently), the careers that lead here are lined with soul-draining bureaucracy and meaningless endeavors that do not satisfy anyone or anything except a quota put forth by higher powers. I can see...

"Really, nobody took a step back and asked..." And then proceeds to present extremely non-trivial physical chemistry. I find that many such parameters go undiscovered because many synthetic groups simply lack the know-how for such studies. Good others take initiative.

Purity of x% usually just means "we made sure it is x% pure, we literally have no conclusive data on the remaining percents". Also 0.1% anything should be inconsequential.

I mean salt for technical use, like for water softening (dish washers) or deicing, should be cheaper than food grade table salt.

Can't you use general purpose salt (non food grade) containing fewer additives. What does the salt used for dish washers contain aside from NaCl?

Why are you resorting to chemical means rather than simply poking holes? 0.3 mm is just aluminium foil?
