Multiple Choice

Determine the equilibrium expression of the barium nitride solid.

Verified step by step guidance

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.
