Final answer:
Copper (II) oxide, being a basic oxide, will react with an acid such as H2SO4 (sulfuric acid) to form copper (II) sulfate and water. It is less likely to react with another basic compound such as K2O or with an alkali like NaOH.
Step-by-step explanation:
The interaction of Copper (II) oxide depends on the reactivity with other compounds. When looking at the given options, Copper (II) oxide will most notably react with acidic solutions, so among the provided choices, Copper (II) oxide would interact with H2SO4, which is sulfuric acid. This is because metallic oxides generally react with acids to form a salt and water.
In the context of the given options related to Copper (II) oxide:
- K2O - It is a basic oxide and would not typically react with another basic oxide like Copper (II) oxide.
- Na2CO3 (sodium carbonate) - While it's a salt of a weak acid, carbonate ions tend to form precipitates with divalent metal ions like Cu2+, leading to the formation of a solid such as copper carbonate.
- H2SO4 (sulfuric acid) - Copper (II) oxide, being a basic oxide, would react with sulfuric acid to form copper (II) sulfate and water.
- NaOH (sodium hydroxide) - It is an alkali, and while not a typical reaction, under certain conditions, complex salts could be produced.
