Mayhem replied to the thread Molecular-level explanation of macroscopic phenomena: dissolving.You are describing recrystalization. The obtained crystals (if any) may have a different phase than the initial solid (crystal or not)... -
Mayhem replied to the thread How to reduce tin?.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... -
Mayhem replied to the thread How to make Sodium Chlorate by Electrolysis of salt water?.It sounds like your problem isnt electrochemical but simply chemical. You are generating chlorine which is the precursor to your target... -
Mayhem replied to the thread Dissolving silver.Are you refining silver for purposes other than exploring science? Silver, unlikely gold, is actually fairly cheap and refining silver... -
Mayhem replied to the thread I am writing a SciFi story but I don't like Rayguns.If you have a sufficiently advanced civilization, then a projectile with an antimatter and matter compartment that combines upon impact. -
Mayhem replied to the thread How to make Sodium Chlorate by Electrolysis of salt water?.How are you identifying chlorine gas? For the record, producing 'lots of chlorine gas' is a serious safety hazard in itself! Anyhow, by... -

Mayhem replied to the thread Chemists finally know why palladium beats nickel at C–H activation."Really, nobody took a step back and asked..." And then proceeds to present extremely non-trivial physical chemistry. I find that many... -
Mayhem replied to the thread Humidity of a saturated NaCl solution with anticaking additive.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%... -
Mayhem replied to the thread Humidity of a saturated NaCl solution with anticaking additive.I mean salt for technical use, like for water softening (dish washers) or deicing, should be cheaper than food grade table salt. -
Mayhem replied to the thread Humidity of a saturated NaCl solution with anticaking additive.Can't you use general purpose salt (non food grade) containing fewer additives. What does the salt used for dish washers contain aside...
