Which statement is not true for electrolysis?

Options

A. Cations migrate towards cathode
B. Anions discharge at anode
C. Anions get reduced during electrolysis
D. Cations get reduced during electrolysis

Explanation

To determine which statement is not true for electrolysis, let's analyze the process step by step.

### Step 1: Understand Electrolysis
Electrolysis is a chemical process that uses electrical energy to drive a non-spontaneous chemical reaction. It typically involves the breakdown of an electrolyte into its constituent ions.

**Hint:** Remember that electrolysis involves an anode and a cathode, where oxidation and reduction occur.

### Step 2: Identify the Components
In an electrolytic cell, we have:
- **Anode**: The positive electrode where oxidation occurs.
- **Cathode**: The negative electrode where reduction occurs.

**Hint:** Oxidation occurs at the anode, and reduction occurs at the cathode.

### Step 3: Analyze Ion Movement
- **Cations (positive ions)** migrate towards the cathode (where reduction occurs).
- **Anions (negative ions)** migrate towards the anode (where oxidation occurs).

**Hint:** Remember the mnemonic: "Anions go to Anode" and "Cations go to Cathode."

### Step 4: Evaluate the Statements
Now, let's evaluate the statements given in the question:
1. **Cations migrate towards cathode** - This is true.
2. **Anions discharged at anode** - This is also true.
3. **Anions get reduced during electrolysis** - This is NOT true; anions are oxidized at the anode.
4. **Cations get reduced during electrolysis** - This is true.

**Hint:** Focus on the definitions of oxidation and reduction to determine the truth of the statements.

### Step 5: Conclusion
The statement that is not true for electrolysis is: **"Anions get reduced during electrolysis."** Instead, anions are oxidized.

**Final Answer:** Anions get reduced during electrolysis (this statement is not true).
