Verified step by step guidance1
Identify the chemical formula of barium nitride, which is Ba3N2.
Write the dissociation equation for barium nitride in water: Ba3N2(s) ⇌ 3Ba^{2+}(aq) + 2N^{3-}(aq).
Understand that the equilibrium expression for the solubility product (Ksp) is based on the concentrations of the ions in solution.
For the dissociation of Ba3N2, the Ksp expression is: Ksp = [Ba^{2+}]^3[N^{3-}]^2.
Note that solids are not included in the equilibrium expression, so only the aqueous ions appear in the Ksp expression.
