The compound potassium sulfide is a strong electrolyte. Write the transformation that occurs when solid potassium sulfide dissolves in water. Use symbols to specify states such as (aq) or (s).

K₂S(s) → 2K⁺(aq) + S²⁻(aq)

Explanation:

A strong electrolyte is a compound that, in solution, dissociates completely. For a compound XₐYₙ that dissolves in water:

XₐYₙ(s) → aXⁿ⁺(aq) + nYᵃ⁻(aq)

Now, potassium sulfide (K₂S), as a strong electrolyte dissolves in water thus:

K₂S(s) → 2K⁺(aq) + S²⁻(aq)
