Question

Classify the following as either an anion or a cation.
Na+ H₃O+ CN- CrO₄₂- Cu+ H₃O+ C₇H₇+ Cl⁻

Answer 1

The species Na+, H₃O+, Cu+, H₃O+, and C₇H₇+ are cations with positive charges, while CN-, CrO₄²-, and Cl- are anions with negative charges.

Step-by-step explanation:

To classify each given species as either an anion or a cation, we will look at the charge each one carries. Here's the classification:

• Na+: Cation
• H₃O+: Cation
• CN-: Anion
• CrO₄²-: Anion
• Cu+: Cation
• H₃O+: Cation
• C₇H₇+: Cation
• Cl⁻: Anion

Anions have a negative charge, while cations have a positive charge.
