Crystallisation Question The idea of crystallisation to purify materials is to get the most product out of the solution. Whil ...	14-7-2017 at 02:35 by: nezza
Drying Ethanol You can't dry ethanol with sodium. It reacts to form sodium ethoxide and hydrogen. The problem with ...	11-7-2017 at 06:34 by: nezza
Cobalt Oxalate Precipitation The precipitation is slow so from dilute solutions you may just have to wait a while.	8-7-2017 at 06:20 by: nezza
Cobalt Oxalate Precipitation I have a few observations on Cobalt Oxalate. Adding stoichiometric amounts of Oxalic acid to Coba ...	8-7-2017 at 04:02 by: nezza
Testing manganese metal The usual tests for the presence of Manganese (as Mn2+) are to acidify the solution with dilute sulp ...	4-7-2017 at 07:10 by: nezza
Reaction of KMnO4 with Iodine Tincture In alkaline solution iodide does reduce permanganate to manganate. If permanganate is added dropwise ...	29-6-2017 at 01:47 by: nezza
Cobalt Oxalate complexes The cobalt(III) carbonate complex is easy enough. Mix cold sodium bicarbonate solution with dilute ...	28-6-2017 at 02:36 by: nezza
Cobalt Oxalate complexes I have made some Cobalt(III) complexes before including the carbonate which is bright green. I have ...	25-6-2017 at 22:53 by: nezza
QUIZ: Can you name all the elements of the periodic table starting with 'C'? 12/12. Copernicium took a while to remember.	15-6-2017 at 23:38 by: nezza
cleaning vanadium Thanks Guys. I liked the idea of using an organic acid as most are slight reducing agents and will n ...	29-5-2017 at 05:44 by: nezza
cleaning vanadium Thanks for that. I'll give it a go with Nitric acid. I note in the video he says nitric acid will di ...	28-5-2017 at 01:20 by: nezza
cleaning vanadium I have some nice vanadium crystals as part of my element collection. I did not take any particular c ...	27-5-2017 at 23:37 by: nezza
Mixing sodium hydroxide and DL lactic acid Lactic acid is a weak acid. Adding Sodium hydroxide will neutralise the acid and form sodium and lac ...	23-5-2017 at 05:55 by: nezza
Preparation of Copper (I) oxide from copper? If you want a nice easy reducing sugar try honey - it is nearly pure fructose.	18-5-2017 at 01:33 by: nezza
Preparation of Copper (I) oxide from copper? Yup. Dissolve the copper to give a solution of copper (II) ions. Add tartrate and Alkali until you g ...	16-5-2017 at 05:59 by: nezza
Labware and chemicals for Belgium and Europe I've just ordered a few element samples from Onyxmet. Their prices seem pretty reasonable. I'll let ...	5-5-2017 at 01:36 by: nezza
