HOW TO MAKE IODINE(element) By Basco36 all you need is potassium iodide & sulfuric acid, Please use caution if you try this experiment,toxic amounts of hydrogen sulfide will be produced. I really do not recommend anybody to try this who is inexperienced. #1 make a saturated solution of potassium iodide #2 slowly add consentrated sulfuric acid.( dont let the solution get hot, put it in ice to bring it to room temprature). #3 after the reaction is complete wash the iodine crystals with lots of water untill pure as can be, #4 dry the crystals on paper towel then put into sealed container.

#01 Electrolysis Of Sodium Chloride (Cl2 is produced!) By bla287 When electrolysing a solution of NaCl, you'd normally expect water to be oxidized to oxygen and oxonium because of the electrode potentials: Cl2 + 2 e− ⇌ 2 Cl− +1,36 V O2 + 4 H3O+ + 4 e− ⇌ 6 H2O +1,23 V Nevertheless, you can "trick out" the potentials by using a graphite anode and a saturated NaCl solution. The smaller chloride ion can attach to the graphite more easily than the bigger H2O molecule, so the chloride ion will be oxidized to chlorine ("over voltage" effect). However, some of the chlorine produced that way will react with the OH- ions produced by the cathode to form ClO- and Cl- (in succession ClO3- and ClO4- as well), but not all of it, so you can collect some of the chlorine. To reduce such disproportionation effects, HCl can be added. To prove that chlorine has really been produced, I let it react with iron to form yellow iron(III) chloride (FeCl3). So you don't need to melt NaCl if you want to obtain Cl2 (but you have to if you want to get Na). BTW the gas bubbling up from the metal cathode is hydrogen (H2).

Chemistry experiment - KMnO4 + NaOH + sugar By TomIRIDIUM Potassium permanganate solution changes colour when poured into sodium hydroxide and sugar solution. Colours are as follows: - purple (MnO4- ions) - blue (MnO4 3- ions) - green (MnO4 2- ions) - orange (Mn 3+ ions) Tags: chemistry, color, colour, experiment, hydroxide, permanganate, potassium, sodium, solution 1 Downloads - Last from: http://downthisvideo.com/ (Your Blog here!) |
