The drawing on the right molecule is wrong. We have here mesomerie behaviour, the aromatic System is broken in the left Ring. https://upload.wikimedia.org/wikipedia/commons/thumb/2/27/Methylorange_Indicator.svg/480px-Methylorange_Indicator.svg.png

Yes it is

Why more confused? Na, K, Ca are innoble metals. During an electrolysis in aqueous solution these elements travel to the cathode, but instead of the element itself hydrogen will be developed from the water. Cl is an anion and travel to the Anode. Depending of the used material of the electrode, it can be developed as chlorine or it react with the electrode Material and corrodes the electrode. Alkali metal can be obtained by electrolysis of melted salt.

Sodium and a lot of other elements cannot obtained from aqueous solutions. Its a matter of the redoxpotential. Mainly elements with positiv potential can be obtained. Below 0V hydrogen will be developed. So Metal will be plated at cathode. Nonmetal will be developed at Anode. Chlorine will be developed on carbon or gold or platinum. By using of other metal, the Anode will be corode and no chlorine will be developed. Amidoximes Amidoximes such as polyacrylamidoxime can be used to capture trace amounts of uranium from sea water. In 2017 researchers announced a configuration that absorbed up to nine times as much uranyl as previous fibers without saturating. https://en.m.wikipedia.org/wiki/Oxime#Amidoximes

It is one Mg missing, it has to be Mg7Si8O22(OH)2.
-
It should be Mg6Si8O22(OH)2. in Comparison to Na2FeI3FeIII2Si8O22(OH)2.
-
It has to be. 2*1+3*2+2*3+8*4 = 46 to 22*(-2)+2*(-1) = -46

No discussions about pyro technic.

Creating HCL with table salt using electrolysis
chenbeier replied to A.Kurd's topic in Applied Chemistry
Yes. You misunderstood me. I agree what you said. By the way Im a safety officer in the company where I am working for. -
Creating HCL with table salt using electrolysis
chenbeier replied to A.Kurd's topic in Applied Chemistry
What is the difference? Its a request and also a demand. Chemistry work and PSE has to be together. -

That is of course a demand to wear the personal safety equipment, like goggles, gloves, labcoat, etc. ifworking with chemistry. -

You can collect hydrogen and chlorine and burn it to HCl. -
Creating HCL with table salt using electrolysis

The assumption to get HCl is not right. On cathode you will get NaOH and H2, but on Anode you get Chlorine no clean HCl. The Chlorine react with water to hypochlorite and Chloride. Can buy as bleach. The method doesnt work. To get HCl treat NaCl with conc. Sulfuric acid. You get HCl gas what can be dissolved in water. -
One becomes wise by trying. "Aus Versuch wird man klug". Do some tests to see the efficency. I am not sure it will work, because of soloubility of Apatit is very poor. I would grind the material ( egg shell etc.) and put it in your device. Feed it it with sodium flouride solution and compare the contant before and after treatment.

I told you already its wrong in the other forum. The potentials are measured against hydrogen electrode. So is Zinc negativ - 0,76 V. In this table they look on one side for Oxidation and on other side for reduction. Li=> Li+ + e- is + 3,04 V Oxidation But in view of Reduction its opposit - 3,04 V This you can do for every element. But the standard reduction potential are measured against hydrogen. So you cannot mix it. The definition is delta E = Kathode (more positiv potential) - Anode ( more negative potential)
-
I think you have to test it. Also to Check if Dimethylcarbonate dont harm the poly styrene. I would start with 10 %.

You didn't Download the right document. On the first Page blue Button 473 PDF Here the right document synthesis of benzyl.pdf
-
Did you Download the PDF, there is ammonium nitrate used.
-
Cu2+ works as oxidiser. https://en.m.wikipedia.org/wiki/Benzil https://pubs.acs.org/doi/10.1021/ed065p553 Download the PDF from there

Neither nor, the volume is given of the container and is constant. The volume of the salt calculate before explosion.

Rate laws of some chemical reactions
chenbeier replied to Dhamnekar Win,odd's topic in Applied Chemistry
Confusion with K equilibrium constant and k constant of rate law.
