Nickel(ii) chloride dissolves in water to form a light green solution. what ions are present in solution—that is, what is "swimming around" in the aqueous solution? write the formulas

Hello!

The ions that are present in solution are Ni⁺²(aq) and Cl⁻(aq)

Why?

When an ionic substance like Nickel Chloride (NiCl₂) dissolves in water, it dissociates into the individual ions that form the substance. Water molecules surround then the individual ions in a process called solvation.

It can be represented in the following chemical equation:

NiCl₂(s) → Ni⁺²(aq) + 2Cl⁻(aq)

Have a nice day!
