When electric current pass through water.Which gases r obtained as anode and which obtain as cathode?
When an electric current passes through water, hydrogen gas is obtained at the cathode (negative electrode) and oxygen gas is obtained at the anode (positive electrode) through the process of electrolysis.
When electric current is passed through water which gas is produced on cathode?
When electric current is passed through water, hydrogen gas is produced at the cathode. This is because water molecules (H2O) are split into hydrogen (H2) and oxygen (O2) gases through electrolysis. The hydrogen gas is evolved at the negative electrode, which is the cathode.
What happen when electric current passes through acidified water?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What happen when electric current is passed through water'?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What is the meaning of cathode?
The part of a voltaic battery by which the electric current leaves substances through which it passes, or the surface at which the electric current passes out of the electrolyte; the negative pole; -- opposed to anode.
Name parts of a cell and explain how they work together to produce a electric current?
The parts of a cell that work together to produce an electric current are the anode (positive terminal), cathode (negative terminal), and electrolyte. The anode releases positively charged ions into the electrolyte solution, while the cathode receives these ions and releases negatively charged ions. The flow of ions between the anode and cathode through the electrolyte creates an electric current.
What happens when electric current is passed through acidified water?
When electric current is passed through acidified water (a mixture of water and an acid such as HCl), electrolysis occurs. The water molecules (H2O) are split into hydrogen gas (H2) at the cathode and oxygen gas (O2) at the anode. The overall reaction can be represented as: 2H2O(l) -> 2H2(g) + O2(g).
How do you refine silver?
Silver is usually refined through a process called electrolysis. In this process, an electric current is passed through a solution containing silver, causing the silver to be extracted and deposited onto a cathode. This results in purer silver being obtained.
How do you extract aluminun from alum?
One way would be to melt the alum and pass an electric current through it, causing metallic aluminum to separate at the cathode.
What is electrolysis of sodium hydroxide?
It is the process of passing an electric current through aqueous sodium hydroxide so that hydrogen is produced at the cathode and oxygen at the anode.
What happens when electric current is passed through fused sodium chloride?
During this electrolysis are obtained chlorine and sodium.
How can cadmium be obtained in its pure form?
Cadmium is typically obtained in its pure form through the process of electrolysis, in which an electric current is passed through a cadmium salt solution to deposit pure cadmium on the cathode. Another method is the thermal decomposition of cadmium compounds, such as cadmium sulfide or cadmium carbonate, at high temperatures to obtain pure cadmium metal.
