Now, as long as the initial concentration of the acetic acid, c, is significantly higher than the Ksp of the acid, you can use the approximation. c − x ≈ c → valid when c >> Ksp −−−−−−−−−−. In this case, the equation becomes. Ksp = x2 c. which gives you. x = √c ⋅ Ksp. Since x ... dust walk off mats orange
