Answer

To solve the question regarding the differentiation among electrolytes and non-electrolytes, strong and weak electrolytes, anode and cathode, and electrolytic dissociation and ionization, we will break down each part step by step.

### Step 1: Differentiate between Electrolytes and Non-Electrolytes
- **Electrolytes**: Substances that dissociate into their constituent ions when dissolved in water.
- **Example**: Sodium chloride (NaCl) dissociates into Na⁺ and Cl⁻ ions.

- **Non-Electrolytes**: Substances that do not dissociate into ions when dissolved in water.
- **Example**: Methane (CH₄) does not dissociate into ions.

### Step 2: Differentiate between Strong and Weak Electrolytes
- **Strong Electrolytes**: Substances that completely dissociate into their constituent ions in solution.
- **Example**: Sodium chloride (NaCl) completely dissociates into Na⁺ and Cl⁻ ions.

- **Weak Electrolytes**: Substances that partially dissociate into ions in solution.
- **Example**: Acetic acid (CH₃COOH) only partially dissociates into CH₃COO⁻ and H⁺ ions.

### Step 3: Differentiate between Anode and Cathode
- **Anode**: The positively charged electrode where oxidation occurs. Negative ions (anions) migrate towards the anode.

- **Cathode**: The negatively charged electrode where reduction occurs. Positive ions (cations) migrate towards the cathode.

### Step 4: Differentiate between Electrolytic Dissociation and Ionization
- **Electrolytic Dissociation**: The process by which ionic compounds dissociate into their constituent ions in solution.
- **Example**: Sodium chloride (NaCl) dissociates into Na⁺ and Cl⁻ ions.

- **Ionization**: The process by which polar covalent compounds form ions when dissolved in a solvent.
- **Example**: Hydrochloric acid (HCl) ionizes to form H⁺ and Cl⁻ ions.

### Summary of Correct Statements:
1. Electrolytes dissociate into ions; non-electrolytes do not.
2. Strong electrolytes completely dissociate; weak electrolytes partially dissociate.
3. Anode is positively charged; cathode is negatively charged.
4. Electrolytic dissociation applies to ionic compounds; ionization applies to polar covalent compounds.
