An electrolyte is always:

Options

A. an acid or alkali
B. an aqueous solution
C. a liquid
D. a molten solid

Explanation

To solve the question "An electrolyte is always:", we will analyze the options provided and determine the correct answer step by step.

### Step 1: Understand the definition of an electrolyte
An electrolyte is a substance that dissociates into ions when dissolved in a solvent (usually water). These ions are charged particles, which can be either cations (positively charged) or anions (negatively charged).

**Hint:** Remember that electrolytes must produce ions in solution.

### Step 2: Analyze the options
1. **Option 1: An acid and/or alkali**
- While acids and alkalis can act as electrolytes, not all electrolytes are acids or alkalis. Therefore, this option is too restrictive.

2. **Option 2: In an aqueous solution, a liquid, or a molten solid**
- This option is broader. An electrolyte must be in a state where it can dissociate into ions. This typically occurs in an aqueous solution (when dissolved in water) or in a molten state (when heated to become a liquid).

**Hint:** Consider the states of matter and how substances behave in those states.

### Step 3: Determine the correct answer
Since an electrolyte must dissociate into ions, it is most accurately described as being in an aqueous solution, where it can freely dissociate into cations and anions. Therefore, the correct answer is:

**An electrolyte is always in an aqueous solution, a liquid, or a molten solid.**

### Final Answer
An electrolyte is always in an aqueous solution, a liquid, or a molten solid.
