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!
