Question

what happens when copper is put into beaker of water​

Answer 1

Answer:

Hydroxide ion (OH-) binds to the copper (II) ion even more strongly than does water. As a result, hydroxide ion can displace water from the copper (II) ion, yielding copper hydroxide, Cu(OH)2, a blue precipitate. Heating copper hydroxide produces copper oxide, CuO, a black solid.

Answer 2

Answer:

• Copper is transition metal.
• It stables in its metallic states
• It forms cuperous (monovalent) and cupric (cation).
• Copper when places in water in presences of oxygen and carbon dioxide.
• When copper is exposed in moist air it turns green
• As moist air is combination of water and CO₂ and O₂ .
• Copper react with water in presence of oxygen and carbondioxide it undergoes oxidation and reduction .
• And copper hydroxide and copper carbonate forms.
• 2Cu + H₂O +CO₂+O₂ → Cu(OH)₂+ CuCO₃.
• It is complete reaction.
• As metal react with O₂ and H₂O to form metal hydroxide.
