A cathode ray produced in a gas-filled tube is deflected by a magnetic field A wire carrying an electric current can be pulled by a magnetic field A cathode ray is deflected away from a negatively?
They are negatively charged
What happen when electric current is passed through slightly acidic water?
Hydrogen gas evolves from the cathode and oxygen gas evolves from the anode.
How do you separate sea water using electrolysis?
The question more or less answers itself. You put an electric current through it and hydrogen forms at the cathode and oxygen forms at the anode.
Metallic aluminum can be obtained by electrolysis of aluminum fluoride dissolved in molten k3alf6. what mass of aluminum is obtained at the cathode if a 5 ampere current is applied for 4 hours?
Also How many grams and what volume of fluorine (@ STP) could be liberated at the anode? Also How many hours would the electrolysis need to continue to produce 75g of aluminum with a current of 15 amperes?
Why flow of current from cathode to anode still the flow of electrons is from cathode to anode?
The direction of current, according to convention, is the direction opposite the direction of electron flow. Remember that the anode is where oxidation occurs, so electrons are lost by the anode. These electrons then move from the anode, to the cathode by a wire that usually connects the two compartments. To reiterate, the electrons flow from the anode (site of oxidation) to the cathode (site of reduction). Because electrons flow from anode to cathode, by convention the direction of current is from cathode to anode (the direction opposite the flow of electrons). Hope this helps!
When electric current is pass through water which gas is obtained from cathode?
oxygen and hydrogen gas
When electric current is passed through water which gas is produced on cathode?
When an electric current is passed through water oxygen gas is produced on cathode because oxygen is positive and cathode is negative . So, oxygen is produced.
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 happen when electric current passes through acidified water?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What happens when electric current is passed through acidified 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.
Why is galvanometer used when you know that electric current travels from cathode to anode of the battery?
I think that you talk about the usage of galvanometer in photoelectric emission experiment. Right? The main purpose of using a galvanometer is to know about whether current flows or not and also the direction in which current flows. Moreover current flows right from anode to cathode and electrons do flow from cathode to anode within the discharge tube.
A cathode ray produced in a gas-filled tube is deflected by a magnetic field A wire carrying an electric current can be pulled by a magnetic field A cathode ray is deflected away from a negatively?
They are negatively charged
What happen when electric current is passed through slightly acidic water?
Hydrogen gas evolves from the cathode and oxygen gas evolves from the anode.
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 is the term for the flow of electric charge?
the electrons goes from the anode to a wire making the anode positive then goes to the cathode making the cathode making it negative SO WHY DO U CARE IS THE WORLD GONNA ENDI WOULD PERFER ENGLISH PLEASE DO U
