...hello,
two short questions
1.....up to which concentration does hot sulfuric acid dissolves silver ? - or must the sulfuric be 96 % ?
2.....solubility of silver sulfate in water is approximately 8 g / litre ---- now i've found that you can get silversulfate in sulfuric acid (80g Ag2SO4 per litre ) for COD-test (chemical oxygen demand) - question is how much silversulfate is max. soluble in conc. sulfuric (approximately)
thanks a lot
