Question

What is the charge of copper ions in water solutions?

Answer 1

Answer:

$Cu^{+}\\\\Cu^{2+}$

Explanation:

Hello.

In this case, since copper has two oxidation states, +1 and +2 in which it indicates the loss of one and two electrons at it outer shell respectively, we can infer that the possible ions of copper in water or aqueous solutions are:

$Cu^{+}\\\\Cu^{2+}$

Which are known as copper (I) or cuprous and copper (II) or cupric positive ions (cations).

Best regards.

Answer 2

The copper ions have +1 and +2 charge in the water solution.

Copper ions in aqueous solution:

The copper has variable valence.

Therefore it has two oxidation states, +1 and +2 which means it has two possible ions, one with a single positive charge and the other with a double positive charge.

So the possible ions of copper in water or aqueous solutions are:

Cu⁺ , with a single positive charge, and

Cu²⁺ or Cu⁺⁺, with a double positive charge

The Cu⁺ ions are known as copper (I) or cuprous positive ions and

The Cu²⁺ions are known as copper (II) or cupric positive ions.

Thus, we can say that in a water solution the copper ions have a +1 and +2 charges.
