Hey, could you help me with this reaction ASAP? I used this recipe: but no bromine was being formed do you know where I could be going wrong? Furthermore, the ferroin solution wasn't changing colour and no oscillations was being created and the H2SO4 was reacting quite a lot unlike yours. Solution a: 11g of KBrO3 100ml of distilled water Solution b) 2g of CH₂(COOH)₂ 75ml H2SO4(10%) 1g of NaBr Fill it to 100ml In 100 ml volumetric flask Solution 3) Ferroin (0.025 mol/L concentration) Mix Solution 1 and 2 in a 1:1 ratio. Add 25 ml of both in a beaker. Note: Bromine should be formed immediately so cover it with a watch glass. Then, add about 1.6 ml of Ferroin once the solution becomes colourless. The duration between colour changes should be about 2 minutes. At the end of the reaction, the solution should remain blue. Then, mix 10 ml of each solution and add ferroin via a pipette. Add everything to a petri dish. Your help would be greatly appreciated. I need your help ASAP

I used silver nitrate and sodium citrate to make silver citrate, which resulted in a clear solution which produced white crystals. Is the silver reduced here because of the heat and/or stoichiometry? I've made silver nanoparticles with a few different methods, but mostly with electrolysis, producing a range of concentrations up to completely opaque. At a certain concentration, it resembles anti-freeze. I didn't know about the infrared properties though, that's pretty interesting. Thanks!

@RaExpIn Ай бұрын

The silver should be reduced in every combination, but the low concentrations and stirring lead to the formation of the round particles. The heat is just to increase the speed of the reaction. If the concentrations are higher, it's possible for one or both of the compound to crystalize on cooling or large crystals of silver are formed as a precipitate. Electrolysis to make silver nano particles sounds quite interesting. Are these spherical particles? I wonder how they form at the cathode and are removed. I would have guessed, that there would always be just crystals forming in electrolysis.

@WaffleStaffel Ай бұрын

@@RaExpIn @RaExpIn I just followed some colloidal silver methods. I've used glucose and cinnamon extract as capping agents, using low current and strong stirring. I cut a silver round in half for the electrodes, and used a small timer and DPDT relay to alternate the anode and cathode a couple times a minute, so I could wear on both halves evenly and avoid contamination from other metals. For the citrate, I followed _"Synthesis and Antimicrobial Activity of Silver Citrate Complexes"_ I use the citrate as a deodorant.

It's a diluted solution of the iron thiocyanate complex as a comparison. To the left more thiocyanate solution was added and to the right more iron(III) solution. Both cause the equilibrium to shift to the right side of the equation.

I wanted to show the experiment on my channel at the time, but the effect was hardly noticeable in the video because my camera unfortunately always defocuses when there are short, weak lighting effects in the dark. A more harmless and simpler version without toxic chlorine gas but with just as strong a glow can be obtained by dripping the hydrogen peroxide solution onto solid calcium hypochlorite.

@RaExpIn 7 ай бұрын

Filming in such low-light conditions is always difficult, when you want to get the best quality as possible. I usually put the focus on manual in the light and then adjust the ISO and other variables to get a bright, but not too grainy shot of the experiment. In addition to that I try to make the experiment emit as much light as possible, which is often just depending on concentrations. Dropping the peroxide on the solid TCCS also works, but I decided to not show too many variations :)

@experimental_chemistry 7 ай бұрын

I can't switch off the autofocus of my camera... 🙁 The glow is much more extensive with calcium hypochlorite than with TCCA.
