I've been wondering about why does carbon get destroyed when used as a anode in most conditions its used there isnt anthying that can react with it yet it falls apart, i search for it but the only result i found says that its because carbon is porous but then the Cathode would fall apart too but it doesnt.
@ScrapScience
@ScrapScience Күн бұрын
The porosity does come into it, but it's not the main reason behind the degradation. When used as an anode, a very small amount of carbon is able to be oxidised to form CO or CO2. Since these electrodes have a porous structure, this oxidation can happen inside the electrode instead of just on the surface, causing them to disintegrate. Without any oxidation, no disintegration occurs. Likewise, making the electrodes less porous (i.e. HOPG electrodes) leads to much less electrode damage (but not zero).

@@ScrapScience Thanks for the reply, that does make a lot of sense. This means that carbon will fall apart faster when making Oxygen like when used in a NaOH solution then when its making cl2?
@ScrapScience
@ScrapScience Күн бұрын
Correct. When making chlorine from aqueous solution, carbon will fall apart slower (but it will still eventually disintegrate, since there's still water present that could lead to the formation of oxides).

As the lithium comes out of the special percentages LiCl-KCl mix, more of the KCl would remain. This would necessitate the mix temperature to be higher wouldn't it, making the operation a little more difficult to succeed with?
@ScrapScience
@ScrapScience Күн бұрын
I agree. Removing lithium from the melt increases the melting point of the eutectic. In this particular experiment, removing less than a gram of lithium really wouldn't have changed much, but it is certainly something to consider for longer runs.

I think electrolysis was used in the Grand Gallery of the Great Pyramid. The resulting hydrogen gas and oxygen gas were ignited which produced a vacuum. That vacuum in the Grand Gallery was used to move water higher in the Grand Gallery. Do you know of anyone who has ignited hydrogen and oxygen gasses in an enclosed cylinder to create a vacuum to lift water higher in the cylinder?

You need to dissolve the salt while the water is at boiling temperature, not beforehand. You also need to use only just enough water to get everything to dissolve - having too much water won't allow anything to crystallise.

​@@ScrapScience I have seen your chlorate cell videos and you should be careful, because Ir-Ru MMO anode can release RuO4 when your cell has high ph(11-14). Your chlorate cells werent ph controlled and had around ph 11. I am not saying that this always happens, but you should be careful.

Factories make Sodium Chlorate NaClO3 in 100 ft square tanks 6 ft deep the anode is .2 to .3 amp per square inch, cathode is .1 amp per square inch 4 volts DC. At 44° C salt is dissolved current efficiency is 80% cool to 25°C efficiency is 85%. NaCl +3H2O + 6 Faradays = NaCl3 + 3H2. Cool solution NaCl is crystallized out until solution becomes concentrated NaClO3. At 20°C NaCl03 crystallized out and removed. A factory can make 250 tons of NaClO3 per month.

I'm sorry if I'm asking too many questions but you mentioned that a Platinum anode is not resistant to HCl, HCl can form at anode chamber when doing membrane electrolysis of NaCl would that degrade it too or are the amounts forming too small to cause damage?
@ScrapScience
@ScrapScience 17 күн бұрын
It ultimately depends on how you run the electrolysis in that case, but yes, the concentrations of HCl generated under membrane electrolysis of NaCl are not high enough to degrade a platinum anode very quickly. The rate of platinum degradation for chloride electrolysis is going to be a function of pH. With lower pH, the rate increases exponentially.

About ten years ago I had to buy some very basic equipment in order to prepare metal etchants for determining the microstructure. Basically, we had to register the company with the DEA, list the equipment that we would be purchasing, describe what it would be used for and where it would be located and utilized.

Thank you for sharing this, very fascinating. I love this salt bridge idea! I'm going to try and make one this week. I'm going to try to find you video of how you made it, but in case i don't find it. do you think its a good idea to reach maximum saturation with the sodium chloride before adding it to the gelatin? Also i should mention you grabbing water from the river could have been the mistake on your 2nd experiment. i did a similar thing a couple of months ago and didn't realize that sea water has a number of other salts in the mixture like magnesium, potassium, and calcium. all of those can make their own hydroxide groups and would be competing reactions. slowing down and/ or stopping some reactions from taking place. I'm no chemist but i would guess calcium being the most reactive is going to be the most problematic.
