Copper oxide is unsoluble in water. A requirement for an alkali is: a soluble base. So copper oxide is a base but not an alkali.
Copper oxide is not considered an alkali. Alkalis are bases that dissolve in water to produce hydroxide ions, while copper oxide is a basic oxide that does not dissolve in water to form hydroxide ions.
Black copper oxide powder is a base because it can react with acids to form salts and water.
Copper oxide is neither an acid nor an alkali. It is considered a basic oxide because it reacts with acids to form salts and water.
Calcium oxide is a BASE. An Alkali is a soluble base. Calcium oxide per se, is not very soluble.
Copper oxide is a base, since it neutralises dilute acid.

No. Copper oxide has no acid-base properties.
The reaction between copper oxide and sulfuric acid is a chemical reaction that results in the formation of copper sulfate and water. This is an example of an acid-base reaction, where the acid (sulfuric acid) reacts with the base (copper oxide) to form a salt (copper sulfate) and water.
Sodium hydroxide is commonly used to make copper sulfate from copper oxide, which is insoluble in water. The reaction between copper oxide and sodium hydroxide forms copper sulfate and water.
Carbon dioxide is neither an alkali nor a base. It is actually an oxide of carbon, and in aqueous solutions, it forms carbonic acid (H2CO3) by reacting with water.
I think you mean how do you extract copper from copper oxide, if so here's your answer. Take your copper oxide and heat it with something that is more reactive than copper. Carbon is a good example. The more reactive carbon will oxidise, taking the oxygen from the copper oxide leaving copper. copper oxide + carbon --> copper + carbon dioxide 2Cu0 + C --> 2Cu + CO2
A BASE is a metal oxide. A soluble base is an ALKALI and contains hydroxide ions. (-OH) Sodium oxide (Na2O) is a BASE Sodium hydroxide (NaOH) is an ALKALI. The alkali comes about because the sodium oxide dissolved in water to form the alkali. Na2O + H2O = 2NaOH .
