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
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.
DOES THE WATER CYCLE CLEAN THE WATER?
Yes, water cycle cleans the water. Rain water is purest form of water.
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
Where does the hydrogen we use as a fuel come from?
Some industrial chemistry gives hydrogen as a by product fro example the electrolysis of brine (salt water) would give hydrogen. We can also electrolyse water to give hydrogen for fuel.
What gas is produced at the cathode of an apparatus used to electrolyse aqueous sodium chloride in the laboratory?
oxygen
How can you convert CaCO3 to Ca?
Add a reflux agent (CaF2) and electrolyse in a cell.
How do you separate chlorine from salt?
Electrolyse the molten salt. This will form sodium at the cathode and Cl2 at the anode. Electrolysis of an aqueous solution odf salt will produce hydrogen at the cathode and chlorine gas at the anode.
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.
If you grounded the electroscope what does that do to the leaves of your electroscope?
...Guys...This is the answer of question...it simple! If we grounded the electroscope..whatever the charge on leaves are, positive or negative (as it depends with which charge you electrolyse the electroscope), if its positive and ground is negative (attraction) or if same + + so repultion
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.
What energy is required to begin a chemical reaction?
Your answer is asked on a too broad spectrum. A brief explanation: A chemical reaction is a reaction where certain molecules are reformed to other molecules. To split Water (H2O) into H2 and O2, it needs to be heated to 1800 C, requiring approximately 7524 Kj. However; Sodium (Na) is an alkaline metal, which produces a chemical reaction when it merely touches air or water. PS: Water is more often split with electrolyse (with electricity) than with thermolyse The general sort of energy required is the activation energy. Which can be all kinds of energy.
The cost of making sodium hydroxide includes the cost of the raw materials used what other costs involved in making sodium hydroxide?
To make sodium hydroxide, you need to electrolyse the solution of sodium chloride. Electricity is needed for electrolysis and that will cost money. There will also be the cost of equipment such as electrodes. (Electrodes have to be replaced after a while). Lastly, there may also be the cost of labour. The men who make sodium hydroxide will need to get paid.
