In a beaker with 1000 ml water dissolve 20 g of picric acid and heat to 80 C with a magnetic stirrer. Than in small amounts add 25 g of sodium
carbonate and let dissolve all. (fumes bubble of) than add to the mixture 30 g of sugar and heat the mixture additional 60 minutes. The colour must go
to red brown.
Than cool to 0-1 C for 4 hours and filter out the brown neddles of potassium picramate and wash with a little amount of destilled water (water
solouble).
the synthesis can be used for the potassium picrate synthesis without the addition of sugar !

Edited twice, and <b>STILL</b> gets <i>POTASSIUM</i> Picramate from <i>SODIUM</i> carbonate. !!!
Was Krypton bored this afternoon or something?

Either Krypton is bored, someone has taken over his account, or he is trying to get on Vulture's bad side. Krypton Krypton fuerchte dich...
