Why CuO isnot dissolve in water?
Copper(II) oxide (CuO) does not dissolve in water because it is a basic oxide that reacts with water to form copper hydroxide (Cu(OH)2), which is insoluble in water. This reaction occurs slowly, preventing CuO from dissolving readily.
What is the reaction of metallic oxide with water?
Reaction of a metal oxide with water produces a metal hydroxide, which is a strong base
What are elements of cuso4?
Copper(II) sulfate, or CuSO4, consists of three elements: copper (Cu), sulfur (S), and oxygen (O). Copper is a transition metal, sulfur is a non-metal, and oxygen is a reactive non-metal. In its pentahydrate form (CuSO4·5H2O), it also includes water molecules, contributing to its crystalline structure and blue color.
Why can't copper replace iron in salt water?
Copper is less reactive than iron, therefore iron will exist as an aqueous ion and copper will be an elemental metal. See the "reactivity series for metals."
What metal group would copper be an example of?
A metalA name that police officers are calledA colorA native mineralA preferred metal for wiring and plumbingThe end product of ore refiningCopper is an example of a transition metal.
what will happen if copper metal is added to copper nitrate?
Copper metal "dissolves" in nitric acid (HNO3). Actually, the nitrate ion oxidizes the copper metal to copper (II) ion while itself being transformed to NO2 gas in the process; the copper (II) ion then binds to six water molecules.
What happens when water is added to a metal halide namely SnI4?
When water is added to a metal namely SnI4, nothing will happen. Both water and metal will remain at its normal state.
What would happen if you added copper sulphate to water at room temperature?
Copper sulfate is soluble in water and dissociated in ions (Cu2)+ and (SO4)2-.
Name the gas produced when nitric acid is added to copper metal?
Nitric acid reacts with copper metal to produce nitrogen dioxide gas, along with water and copper(II) nitrate.
What happen when metal is added to water?
it depends what metal it is, if it is a reactive metal like potassium or sodium it will effervesce (bubble) and create a metal hydroxide and hydrogen. if it is a less reactive metal it will create a metal oxide and hydrogen (zinc, etc)
Why does the water colour change to blue when copper sulphate was added?
Anhydrous copper(II) sulphate is white. When added to water, it forms a solution of CuSO4(aq) which is blue because of the Cu2+ ion, which is itself a transition metal ion.
When water is added to white copper and copper sulphate why is it a chemical change?
When water is added to white copper (zinc) and copper sulfate, a chemical change occurs because new substances are formed. The zinc displaces the copper in the copper sulfate solution, leading to the formation of zinc sulfate and copper metal, which are chemically different from the original substances. This reaction is a classic example of a single displacement reaction.
What happens when you mix copper II chloride in water and then add aluminum folio into the mixture?
When aluminum foil is added to a solution of copper (II) chloride in water, a displacement reaction occurs where the aluminum reacts with the copper (II) ions. This results in the formation of aluminum chloride and copper metal. The copper metal will appear as a solid precipitate in the solution.
What is the metal for water pipes?
Copper
When copper sulfate is added to water it .......to form a?
Why does copper sulfate change its colour when water is added
What are the colors of silver metal and copper nitrate in water?
The colour of silver metal in water is whiteThe colour of copper nitrate in water is blue (due to the Cu++ ion).
What happens to copper sulphate when added to water?
When copper sulphate is added to water, it dissociates into copper ions (Cu2+) and sulphate ions (SO4 2-). This forms a blue-colored solution due to the presence of copper ions in the water.
