Question

Identify an acidic flux among the following.

• A. \(SiO_2\)
• B. \(CaO\)
• C. \(MgO\)
• D. \(CaCO_3\)

Answer 1

The Correct Option is A

To solve the problem, we need to identify the acidic flux among the given options.

1. Understanding Acidic Flux:
An acidic flux is a substance that has acidic properties, typically forming acidic oxides or dissolving in water to release acidic ions. These substances generally react with basic materials to form salts.

2. Analyzing the Options:

- SiO₂ (Silicon dioxide) is an acidic oxide and forms acidic solutions when dissolved in water, making it an acidic flux.
- CaO (Calcium oxide) is a basic oxide and acts as a basic flux.
- MgO (Magnesium oxide) is also a basic oxide, thus a basic flux.
- CaCO₃ (Calcium carbonate) is neither a pure acidic nor basic oxide, but can act as a neutral flux in certain conditions.

3. Final Answer:
The acidic flux among the options is $ \mathbf{SiO_2} $.
