What are the disadvantages of using salt water to conduct electricity?
electrolysis of water could ensue, blocking conductivity
What chemical properties do the products of electrolysis have that are produced by the decomposition of water?
They don't have any properties!
How can define fusion regarding welding?
Fusion is the melting and mixture of base metal to the melted filler material (Rod or Electrode). It takes place in the puddle and is the Weld. Sorta like making mud by adding water to dirt. If they don't mix there is no mud.
Which material will float on water?
The material which are less denser than water will float on water..!!
What can you infer about the density of a material if a sampleof it floats in water?
That the material's density is less than the density of water.
How is electrolysis of water used?
Electrolysis, passing an electric current, through water separates the water into its elements: oxygen and hydrogen. When Direct Current (DC) is used, oxygen precipitates (comes out of) the water at the positive electrode and hydrogen precipitates at the negative electrode.
How will you test the gas collected in electrolysis of water?
pop test for hydrogen at -ve electrode glowing splint test for oxygen at +ve electrode
Is it possible to remove hardness of water by electrolysis?
Yes. The dissolved cations are reduced and form a solid plating on the electrode.
How can water be converted into its original elements?
One way to convert water into its constituent elements is by electrolysis. Electrolysis is done by putting a positive and a negative electrode into the water and passing a direct current through the water. The hydrogen and oxygen will turn into their elemental gasses.
What is the best electrode material for the electrolysis of water?
platinum Expanding on the answer above, the best material for an electrode really depends on the application. When looking at electrode materials, you need to consider three factors: 1. Electrical Conductivity- Different materials resist the flow of electric current through them at varying levels. Copper, Gold, and Platinum are very good conductors. Alloys, Steel, Iron, and other metals are good conductors as well. 2. Corrosion Resistance- The electrolysis of water is very corrosive to the electrode material. If you use the wrong electrode material, you will have to replace the electrodes often. Platinum and 316L Stainless steel are the best options as far as corrosion resistance. Copper is very poor at resisting corrosion. 3. Price- Though platinum is probably the best overall choice for electrode material, it is very expensive. When designing a large, high output electrolyser the electrodes need to be large and have a lot of surface area. Making large electrodes out of platinum would not be an option for most. In conclusion, when choosing an electrode material you need to consider the above variables. In my opinion 316L stainless steel is the the best option for home made electrolysers because it is relatively cheap, has high corrosion resistance, and is a good electrical conductor. This material is also available in many different prefabricated shapes and sizes that can be custom fitted to your application. If price is not a concern, then platinum is the best material.
What has the author R A J Dams written?
R. A. J. Dams has written: 'Performance tests on new electrode materials for hydrogen production by water electrolysis'
Can cars run on water?
Yes,if you use electrolysis to diffuse oxygen from hydrogen.You will have to suck the hydrogen from the electrode the compress it to make it a liquid now you can use it as fuel.(This is my invention).
Breakdown of a substance by electricity?
This is named as 'ELECTROLYSIS'. The classic examples are ;- #1; Decomposition of water , using the 'H' pattern electrolyser. into its compoentn gases of hydrogen and oxygen. #2; The electrolysis of sodium chloride solution to form chlorine gas and sodium hydroxide, with the liberation of hydrtogen at the other electrode. #3; The electrolysis of bauxite (aluminium oxide) to form aluminium.
How do you decompose water into hydrogen and oxygen?
Through a process known as electrolysis which seperates them into their own individual atoms. At positive electrode (anode) 2H2O --> O2 + 4H+ + 4e- or 2OH- --> O2 + 2H+ + 4e- At the negative electrode (cathode) 4H+ + 4e- --> 2H2 or 2H2O + 2e- --> H2 + 2OH-
How do you separate H2O atoms?
Electricity will do it. You can use a small battery and a beaker of water. Put a wire from each terminal into the water. The water will bubble as the electricity passes through. One electrode, the (+), or anode, will produce oxygen atoms, the other electrode, the (-), or cathode, will produce hydrogen atoms.The process is called electrolysis. The bubbles can also be collected quite easily (oxygen gas from one terminal, hydrogen from the other), but that is another matter.
Why are substances like platinum and palladium often used for carrying out electrolysis of aqueous solutions?
that is because platinum and palladium are inert elements and they wont react with the substance deposited on the electrode.. unlike if we use carbon electrodes, carbon will react with oygen deposited on it and escape out as CO2 gas
Who discover the electrolysis of water?
William Nicholson and Anthony Carlisle discovered the electrolysis of water in May 1800
