Electrolyte used in voltaic cell is:

Options

A. sulphuric acid
B. acetic acid
C. nitric acid
D. hydrochloric acid

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Voltaic Cell**: A voltaic cell, also known as a galvanic cell, is a device that converts chemical energy into electrical energy through spontaneous redox reactions. It consists of two electrodes (anode and cathode) immersed in an electrolyte solution.

2. **Identifying the Electrolyte**: The electrolyte is a substance that conducts electricity when dissolved in water or melted. In a voltaic cell, the electrolyte allows the flow of ions between the two electrodes, facilitating the chemical reactions that produce electricity.

3. **Common Electrolytes in Voltaic Cells**: Various electrolytes can be used in voltaic cells, but one of the most commonly used electrolytes is sulfuric acid (H2SO4). In concentrated form, it provides a high concentration of ions, which is essential for efficient conduction of electricity.

4. **Conclusion**: Based on the information provided, the electrolyte used in a voltaic cell is concentrated sulfuric acid (H2SO4).

**Final Answer**: The electrolyte used in a voltaic cell is concentrated sulfuric acid (H2SO4).
