The correct Answer is:
To determine the valency of copper in copper sulfate (CuSO₄), we can follow these steps: ### Step-by-Step Solution: 1. **Understand Valency**: - Valency is defined as the combining capacity of an element, which can be determined by the number of electrons an atom can gain, lose, or share when forming a compound. 2. **Identify the Compound**: - The compound in question is copper sulfate, which is represented as CuSO₄. 3. **Analyze the Sulfate Ion**: - The sulfate ion (SO₄) has a known valency. The sulfate ion carries a charge of -2, which means it has a valency of 2. 4. **Determine the Charge of Copper**: - In the compound CuSO₄, the sulfate ion has a charge of -2. To balance this charge, copper must have a charge of +2. 5. **Calculate the Valency of Copper**: - Since copper has a charge of +2 in copper sulfate, this indicates that copper has lost 2 electrons to achieve this charge. Therefore, the valency of copper in copper sulfate is 2. 6. **Conclusion**: - The valency of copper in copper sulfate (CuSO₄) is 2. ### Final Answer: The valency of copper in copper sulfate is **2**. ---
