What is the sign convention for the cathode and anode in an electrolytic cell?
Anode is the positive electrode while cathode is the negative electrode. Negative ions(anions) travel towards the anode(hence the name) Positive ions(cations) travel towards the cathode(hence the name) Example for anode:Copper Example for cathode:Zinc
How do negatively charged plates affect the path of cathode rays?
Negatively charged plates will attract cathode rays, causing them to bend or deflect towards the plates. The extent of the bending will depend on the strength of the electric field between the plates and the voltage applied across them.
How were electrons produced from the cathode ray ube?
Electrons were produced in a cathode ray tube by applying a high voltage to the cathode, causing electrons to be emitted through thermionic emission. These electrons were then accelerated towards the anode by the electric field within the tube, creating a beam of electrons known as the cathode ray.
Which electrode do the copper iron move towards?
Copper ions will move towards the cathode (negative electrode) and iron ions will move towards the anode (positive electrode) in an electrolytic cell.
Why cathode rays are negatively charged?
Cathode rays are negatively charged because they are composed of electrons, which have a negative charge. When a high voltage is applied to the cathode in a vacuum tube, electrons are emitted from the cathode and accelerated towards the anode, creating a beam of negatively charged particles known as cathode rays.
Why is the beam of light called a cathode ray?
The beam of light is known as a cathode ray because historically it was produced in vacuum tubes by directing a stream of electrons from a negatively charged electrode (cathode) towards a positively charged electrode (anode), leading to the term "cathode ray." It was named so in reference to the electrode from which the electrons originated.
What is the anode and cathode of a lead storage battery?
Anode : The end which is at a lower negative potentialCathode: The end which is at a higher negative potentialAnswerThe cathode is the terminal towards which free electrons drift in a cell's external circuit. In other words, when the cell is discharging, it is the positive electrode.
Are cathode rays deflected toward a negatively charged plate in an electric field?
Yes, cathode rays are deflected towards a positively charged plate in an electric field. The negatively charged particles in the cathode rays are attracted to the positive plate, causing the deflection.
In a battery electrons flow from where?
In a battery, electrons flow from the negative terminal (anode) towards the positive terminal (cathode) through the external circuit, creating an electric current.
When cathode rays are passed through a magnetic field which pole do they deflect towards north or south and why?
Cathode rays are electron beams. When they are moving in a magnetic field, they are deviated. The direction of their deflection is given by Fleming's left hand rule. The direction of deflection, current (which is the reverse of the direction of the electron beams) and field are all perpendicular to each other. Hence, the electron beam will deviate in a direction contained in a plane which is perpendicular to both the field and the electron beam. Hence, the cathode rays are neither defleted to the north nor south pole.
What happens when current passes through an electrolyte?
When current passes through an electrolyte, it causes chemical reactions at the electrodes. Positive ions move towards the negative electrode (cathode) and negative ions move towards the positive electrode (anode). This leads to the conversion of the ions into neutral elements or compounds at the electrodes.
Why do certain dyes migrate toward the cathode and others towards the anode?
Molecules migrate to different electrodes depending on the charge they carry. Positively charged dyes migrate toward the anode (the negative electrode) and negatively charged dyes migrate toward the cathode (the positive electrode)
