Text Solution

AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Electrolytic Cell**: An electrolytic cell consists of two electrodes: the anode and the cathode. These electrodes are immersed in an electrolyte solution, and they are connected to a power source. 2. **Identifying the Electrode where Electrons Enter**: In an electrolytic cell, the electrode where electrons enter the solution is known as the **cathode**. This is because the cathode is connected to the negative terminal of the power source, allowing electrons to flow into the solution. 3. **Chemical Change at the Cathode**: The chemical change that occurs at the cathode is known as **reduction**. Reduction is defined as the gain of electrons by a substance, which leads to a decrease in its oxidation state. 4. **Final Answers**: Therefore, the electrode at which the electrons enter the solution is called the **cathode**, and the chemical change that occurs at this electrode is called **reduction**. ---

    Electrolusis involves electronation and de-electronation at the redpective electrodes. Anode of electrolytic cell is the electrode at which de-electronation takes place whereas at cathode electronation is noticed. If two or more ions of same charge are to be electronated or de-electronated, the ion having lesser discharge potential is dischargeed. Discharge potential of an ion refers for E_(OP)^(@) or E_(RP)^(@) as the case may be. The products formed at either electrode is given in terms of Faraday's laws of electrolysis i.e., w = (E.i.t)/(96500) E. 5 litre solution of 0.4 M Ni(NO_(3))_(2) is electrolysed using Pt electrodes with 2.4125 ampere current for 10 hour:
