Question

write the balanced dissociation equation for solid nickel(ii) iodide in aqueous solution. if it does not dissociate, simply write only nr. be sure to include the proper phases for all species within the reaction.

Explanation:

Step1: Identify the compound

Nickel(II) iodide has the formula $NiI_2$.

Step2: Write dissociation in water

In aqueous solution, it dissociates into its ions. The balanced dissociation equation is $NiI_2(s)
ightarrow Ni^{2 + }(aq)+2I^{-}(aq)$.

Answer:

$NiI_2(s)
ightarrow Ni^{2 + }(aq)+2I^{-}(aq)$
