Will an aluminum and a zinc electrode in pure water create a current?

If you put two metal electrodes in an electrolyte, such as salt water, electrons will flow from the less-noble metal to the more-noble one. If you use two electrodes of the same metal, there is no difference in nobility so no current will flow.

When an electric current passed through water which gas is obtained on anode?
The anode is the negative electrode. It produces hydrogen gas.
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 chemical equation for aluminum being dissolved in water?
Aluminum does not dissolve in water.
What materials you need to find the density of aluminum?
You need some aluminum, a scale to determine the mass, and a measuring cup halfway filled with water to determine the volume of the piece of aluminum by substracting the volume after and before you drop the piece of aluminum in the water. Then you can calculate the density of the aluminum = mass / volume.
Why is the pH meter placed in distilled water before testing each solution?
Not the pH-meter, but the electrode.
How do you separate the hydrogen from the oxygen in water?
You pass an electrical current through the water. The positive electrode will release oxygen while the negative electrode will release hydrogen.
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.
Is it possible to run a continuous electric current through water?
Yes, provided there is no breakage in the circuit (the water is completely intact from electrode to electrode) and the water has some salt impurity (there is some salt dissolved in it).
When an electric current passed through water which gas is obtained on anode?
The anode is the negative electrode. It produces hydrogen gas.
How can be obtained?
one way is to pass a current through water (H2O) hydrogen bubbles off at one electrode, oxygen off the other.
How can you prepare hydrogen gas using chemicals?
One simple way is to add aluminum metal to a solution of water and sodium hydroxide (common lye). The lye assists the reaction between aluminum and water, which combines the aluminum with oxygen to create aluminum oxide, and liberates hydrogen.
What is the process or making Hydogen from water?
Water is di-hydrogen oxide (H2O); to make hydrogen, it is necessary to split the hydrogen off from the oxygen. This is most often done by electrolysis. A small amount of acid is mixed with the water to make it conductive, then two electrodes are placed in the water. An electric current is passed through the water from one electrode to the other, and the current breaks the water molecules apart; hydrogen appears at one electrode, while oxygen appears at the other.
Tha water solution of ionic compound are able to conduct an electrical current?
The water solution of an ionic compound is able to conduct an electrical current because of ions migration towards the anode and cathode. Anions give up and electron at the anode and captions take an electrode at the cathode and current keeps moving.
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.
How is flowing water used to create energy?
There are things called turbines that convert the current of the water into electricity.
Which will conduct electric current aluminum foil sugar or potassium hydroxide dissolved in water?
Aluminium foil and potassium hydroxide in water solution are conductors.
Why do tubifex worms wave their tails in water?
these worms wave their tails to create water current to get more air
