True or False?
a) wet metallic copper can be rinsed with acetone to help any remaining cation to metal reduction occur
b)copper metal is readily oxidized by nitric acid to yield copper(II) nitrate
b is true.
a doesn't make sense. If it is copper metal (pure), there is no cation to reduce. So I would answer a as false. However, if this question relates to a lab you are doing, the circumstances can change.
r u sure b) is true b/c it says "readily oxidized" and doesn't the nitric acid have to be very concentrated?
maybe i should have mentioned earlier...one of them is true and the other is false
a) False. Wet metallic copper should not be rinsed with acetone to help any remaining cation to metal reduction occur. Acetone is a flammable solvent and mixing it with a reactive metal like copper can pose a safety hazard. Additionally, acetone is not typically used for this purpose as it does not facilitate cation to metal reduction.
To verify this, you can refer to reliable chemical reference books or scientific literature that provide information on appropriate methods for reducing cations to metals.
b) True. Copper metal is readily oxidized by nitric acid to yield copper(II) nitrate. Nitric acid is a strong oxidizing agent and copper is an easily oxidizable metal. When copper is exposed to nitric acid, it undergoes oxidation and gets converted into copper(II) nitrate.
To verify this, you can perform a chemical reaction between copper metal and nitric acid in a controlled laboratory setting. You can observe the formation of copper(II) nitrate as a blue-colored solution or solid precipitate, indicating the oxidation of copper.
Please note that experiments involving chemicals should only be conducted by trained professionals in appropriate laboratory settings following all necessary safety protocols.
