What else can I help you with?
How do you make hydrogen from salt water?
You need to electrolyse it. Hydrogen will be produced at the cathode.
What gas is produced at the cathode of an apparatus used to electrolyse aqueous sodium chloride in the laboratory?
oxygen
Why is it not possible to electrolyse a solid substance?
It is not possible to electrolyze a solid substance because in order for electrolysis to occur, the substance needs to be dissolved in a liquid or molten form to allow for the movement of ions. Solids do not allow for this movement of ions required for electrolysis to take place.
What kind of water is there?
Tap water Drinking water Sewer water Pipe water River Water Mineral water Pure water Dirty water
Why does water float and sink in water?
Water floats and sinks in water because water in water results in the mixing and diffusion of the water in the other water. This may sound silly, but the question was one dealing with water in water. The mixture of water and water will, after a time, become one homogenous volume of liquid.
Kind of energy in electrolysis of water?
Electrical energy is required to electrolyse water.
How do you make hydrogen from salt water?
You need to electrolyse it. Hydrogen will be produced at the cathode.
How can you electrolyze water?
First make it conduct electricity by adding a small amount of sulfuric acid.then use 2 inert electrodes to electrolyse the electrolyte.remember to collect the gas evolved
What gas is produced at the cathode of an apparatus used to electrolyse aqueous sodium chloride in the laboratory?
oxygen
If you electrolyse 1 gallon of water into hydrogen and then run the hydrogen through a fuel cell how much waste water will the fuel cell generate?
The fuel cell will generate about 1 gallon of waste water. The reaction of hydrogen combining with oxygen in the fuel cell produces water as a byproduct. Since the hydrogen generated from electrolyzing 1 gallon of water would similarly combine with oxygen in the fuel cell to produce water, the amount of waste water will be approximately equal to the original volume of water electrolyzed.
Where does the hydrogen we use as a fuel come from?
Hydrogen used as a fuel can be produced through various methods such as electrolysis of water, steam methane reforming, or through by-product processes in industries like chlor-alkali. These methods allow us to generate hydrogen without relying solely on fossil fuels.
What happens if diluted hydrochloric acid is being electrolyse?
During the electrolysis of dilute hydrochloric acid (HCl) solution, hydrogen gas is produced at the cathode while chlorine gas is produced at the anode. This is because HCl dissociates into H+ and Cl- ions in water, where H+ ions are reduced to form hydrogen gas and Cl- ions are oxidized to form chlorine gas. Water is also electrolyzed, producing oxygen gas at the anode and some hydroxide ions at the cathode.
Why is it not possible to electrolyse a solid substance?
It is not possible to electrolyze a solid substance because in order for electrolysis to occur, the substance needs to be dissolved in a liquid or molten form to allow for the movement of ions. Solids do not allow for this movement of ions required for electrolysis to take place.
Conductivity of liquid of sodium peroxide?
Sodium peroxide will not conduct electricity. Only if in molten state which is electrolyse it will conduct electricity. Causes of the sodium peroxide cannot conduct it is because of there is no freely moving mobile ions.
Which fuel causes minimum environmental pollution. A hydrogen B coal C diesel D kerosene?
hydrogenA2:Coal is the fuel that produces the least pollution among the choices. Hydrogen would be the least polluting except for the reality that hydrogen is produced by burning coal to produce electricity to electrolyse water. Only if the electricity used to produce the hydrogen were produced by hydro, wind or solar, would hydrogen be less polluting than coal.
How can you convert CaCO3 to Ca?
You can convert CaCO3 (calcium carbonate) to Ca (calcium) by heating it at a high temperature in the presence of a reducing agent, such as carbon. This process, known as calcination, will decompose the calcium carbonate, releasing carbon dioxide and leaving behind calcium oxide. The calcium oxide can then be reacted with water to form calcium hydroxide, which can further be processed to obtain pure calcium.
Why is it impossible to electrolyse a solid ionic compound?
It is impossible to electrolyze a solid ionic compound because the ions cannot move freely to the electrodes in a solid state. In order for electrolysis to occur, the ions must be in a molten state or dissolved in a liquid solvent to allow them to be mobile and carry the electric current.
