The correct Answer is:
To solve the question "Thomas slag is", we will analyze the options provided and determine the correct answer step by step. ### Step-by-Step Solution: 1. **Understanding Thomas Slag**: - Thomas slag is a byproduct obtained from the Thomas process, which is used in steelmaking. It is important to identify its chemical composition and properties. 2. **Analyzing the Options**: - **Option 1: Calcium Silicate**: This is a compound consisting of calcium and silicon. It is not typically associated with Thomas slag. - **Option 2: Anode Mud**: This is a residue left after the electrolysis of metals. It does not relate to Thomas slag. - **Option 3: Ferrous Silicate**: This is a compound of iron and silicon. It is also not the correct identification of Thomas slag. - **Option 4: Calcium Phosphate**: This compound consists of calcium and phosphate ions. It is known to be the correct identification of Thomas slag. 3. **Confirming the Chemical Composition**: - Thomas slag is primarily composed of calcium phosphate, specifically tetra calcium phosphate, with the chemical formula \( \text{Ca}_4(\text{PO}_4)_2\text{O} \). 4. **Application of Thomas Slag**: - Thomas slag is used as a fertilizer, particularly beneficial in acidic soils due to its high basic effect. It has a calcium-phosphorus ratio of 2, which is favorable for plant growth. 5. **Conclusion**: - Based on the analysis, the correct answer is that Thomas slag is **Calcium Phosphate**. ### Final Answer: Thomas slag is **Calcium Phosphate**. ---
