Electrolysis Definition and 217 Threads

Sorry I am poor at using English to describe things. I hope you will patiently read my questions and answer them. 1. I saw some helium balloons today. We all know that if you do not hold the helium balloons, they will rise up to the sky. But today I saw a bundle of helium balloons (their...

What substance is produced at the anode during the electrolysis of a mixture of molten calcium bromide and molten magneius iodide?

Hey I got some plans off the internet how to make hydrogen so i built a machine made out of PVC pipe,car battery and two water containers. Sure it makes hydrogen but how do the hydrogen get through the hose. Is it When the hydrogen bubbles pop it let's the hydrogen out than into the...

bigKIDmarie* (下午 03:22) : a passage from my chem textbk: a d.c. power supply acts as an electron pump. if forces electrons from its negative pole to the cathode of the electrolytic cell. the cathode thus has excess electrons and becomes negatively charged. does it mean that the d.c...

Is there ever any electrical activity inside the body, normal or abnormal, minor or major, that results in electrolysis? For instance, there is a large amount of water in our bodies, and although electrolytes may make it conductive, does any of it ever interact with our body's electrical...

Can water molecules be split by simply passing an electric current through water or does it need to be done in a specific manner? Assuming the water solution remains constant, will the results vary depending on materials used for electrodes and does the placement of electrodes affect the outcome?

Electrolysis of Brine... Why does castner-kellner cell produces Na. I was always told that Na formed too stable an ion to be reduced when it is in aqueous solution even when the solution is concentrated. I myself have carried out this experiment by elecrolysing concentrated aq. Sodium...

Can I use potassium fluoride for electrolysis? Instead of KOH, or NaOH. This cell will be operated @ near 90 C, so I want the graphite electrodes to last as long as possible. I just need to know if the fluoride ion can be oxidized in an aqueous solution...I know fluorine gas is usually...

In the electrolysis of Au3+ (aq) solution, gold is deposited. How much gold is deposited in 6 hours by a constant current of 0.540 A? I know you need to find the moles of e- by using It/F. But I'm not sure where to go from there. Any help would be great. Thanks.

What happens if I use copper(II) sulphate as electrolyte with zinc electrode and copper electrode? Can this be an electrolysis set-up? SO2 produced?

Hi i am confused about on how to solve this question. The question asks: By the electrolysis of water, 11.2L oxygen at STP was prepared. a) What charge was required? b) if a current of 0.05A was used, how long did it take? I have done the question but i think i did it wrong. 2H2O(l)...

Today I got the brilliant idea to make my own sodium hydroxide. I put some water in a glass jar, threw in some salt, connected each electrode to a terminal on a 12V DC motorcycle battery, and away the reaction went. My assumption was that the metal breaking apart at the positive electrode...

Electrolysis Of Water Help Please... Hi, I have been trying to raise the Concentration of H2SO4 by using electrolysis. I figure that since the overall reaction will yeild H2 gas and O2 gas (therefore no sulfur is lost) the concentration of the Acid will rise. (If I am correct up to here...

Electrolysis will release the elementary components of a medium, albeit the process required a fare amount of energy, is there any other reasons it would be considered secondary to a more effience process? Does it have any pros?

i have a practical assesment i need to complete at school and i come across this problem...i am to electroplate a 20 cent coin with a layer copper, i have all the experiment setup but I'm a bit confused abit about the faraday formula... one of the calculations i need to work out is the...

I'm trying to put a copper layer on a piece of steel. Here is the equipment I'm using: -12v car battery charger -bucket -water -sodium hypochlorite -copper pipe -piece of steel I filled a bucket with water and added a bit of sodium hypochlorite (bleach). The hypochlorite is there to...

[SOLVED] Kinetics of Electrolysis Can you help me with this problem? Assumptions: 1- Electrolysis of seawater at 1,000 ft. 2- Gases are generated having buoyancy, probably chlorine, hydrogen, oxygen 3- Gases are captured as they rise and mechanically converted to electrical energy to...
