Which element is produced at the negative electrode (cathode)?
The element forming at the cathode will depend on what elements are present. Reduction takes place at the cathode, so whatever element is being reduced, that is the one that will be produced at the cathode.
What following piece of equipment was used by jj Thomson to find electrons?
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.
Where does reduction occur in an electrochemical cell?
The cathode.
How did thomas discover the electron?
J. J. Thomson discovered the electron using an experiment involving cathode rays and a magnetic field. When subjected to the magnetic field, the cathode ray was deflected. If the magnetic field was flipped, the cathode ray was deflected in the opposite direction. This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.
What would be the cathode in Mg and Zn galvanic cell?
In a galvanic cell involving magnesium (Mg) and zinc (Zn), the cathode is the electrode where reduction occurs. In this case, zinc acts as the cathode because it has a higher reduction potential compared to magnesium. Therefore, zinc ions in solution gain electrons and are reduced to solid zinc at the cathode, while magnesium oxidizes at the anode.
What would be formed at the cathode and the anode during the electrolysis of sodium hydroxide solution?
Hydrogen gas would evolve from the cathode and oxygen gas would evolve from the anode.
How do charged plates affect the path of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
How do charged plates affect the plates of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
What would be the cathode in a magnesium and zinc galvanic cell?
The magnesium would be the cathode in a galvanic cell with zinc. Reduction occurs at the cathode during cell operation, and in this case, magnesium is reduced while zinc undergoes oxidation at the anode.
What following piece of equipment was used by jj Thomson to find electrons?
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.
What is a positive electrode?
A positive electrode is a cathode. A negative electrode is an anode.An anode is positively charged, while a cathode is negatively charged.
How can you identify a cathode nigative to an LED?
LED has two pins,one is anode(positive) and the other is cathode(negative).The smaller pin is cathode(negative) and the longer pin is anode(positive).
What was Thompson working with when he discovered the cathode rays?
Thomson discovered cathode rays when he was working with electrons. He was performing experiments with the electrons when one of them became electrically charged and a beam of light came from it, this creating a cathode ray.
What is the cathode ray is emitted from the negative electode called?
That would be electrons.
Should one provide 12volts for charging two 6volt batteries which are connected in such a way that cathode of one battery is connected to cathode of other and anode is also connected in similar manner?
If two batteries are connected in parallel (i.e anode of first with anode of other and cathode of first with cathode of other), then they cannot be charged using 12V, it may damage them.But if anode of first is connected to cathode of other (i.e. Batteries in Series) and cathode of first with cathode of 12 V supply (i.e. cathode of charger) and anode of second with anode of 12 V supply(i.e. anode of charger) then both the batteries can be charged using 12 V supply, easily.
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 effect will a positively charged metal plate have on a cathode ray?
Since a cathode ray is a stream of electrons, and since electrons are negatively charged, a positively charged metal plate would cause a deflection in the cathode ray towards the plate.
