Which of the following facts is true about electrolysis of copper sulp...
Answer:

The electrolysis of copper sulphate solution using copper electrodes involves the passage of an electric current through the solution, resulting in the deposition of copper ions onto the cathode and the dissolution of copper atoms from the anode.

Explanation:

1. Electrolysis Process:
During the electrolysis process, copper sulphate (CuSO4) dissociates into copper ions (Cu2+) and sulphate ions (SO4^2-) in the solution. When an electric current is passed through the solution, the positive copper ions move towards the cathode (negative electrode) and get reduced, while the negative sulphate ions move towards the anode (positive electrode) and get oxidized.

2. Cathode:
At the cathode, copper ions (Cu2+) gain electrons from the cathode and get reduced to form copper atoms (Cu), which are then deposited onto the cathode. This results in an increase in the mass of the cathode.

3. Anode:
At the anode, copper atoms (Cu) lose electrons to the anode and get oxidized to form copper ions (Cu2+). These copper ions then dissolve into the solution, resulting in a decrease in the mass of the anode.

4. Conclusion:
Based on the above explanations, the correct fact about the electrolysis of copper sulphate solution using copper electrodes is:

(b) The mass of the cathode increases, and the mass of the anode decreases.

This is because copper ions are reduced and deposited onto the cathode, increasing its mass, while copper atoms from the anode are oxidized and dissolved into the solution, decreasing its mass.

Read the given passage and answer the questions:Metallic Character: The ability of an atom to donate electrons and form positive ions (cation) is known as electro-positivity or metallic character. Down the group, metallic character increases due to increase in atomic size and across the period, from left to right electropositivity decreases due to decrease in atomic size.Non-Metallic Character: The ability of an atom to accept electrons to form a negative ion (anion) is called non-metallic character or electronegativity. The elements having high electro-negativity have a higher tendency to gain electrons and form anion. Down the group, electronegativity decreases due to increase in atomic size and across the period, from left to right electro -negativity increases due to decrease in atomic size.Which of the following reasons correctly justifies that “Fluorine (72pm) has a smaller atomic radius than Lithium (152pm)”?
