When do I use K_w = [H⁺][OH⁻] = 10⁻¹⁴ in Equilibrium, and what does it mean?
the ion-product of water at 25°C.
K_w = [H⁺][OH⁻] = 10⁻¹⁴ — the ion-product of water at 25°C. Use it when: aqueous solution at 25°C. Always check the condition holds before plugging in numbers.
Key point
K_w = [H⁺][OH⁻] = 10⁻¹⁴
