At a particular temperature, aluminum hydroxide, Al(OH)3, has a Ksp = 2.52×10^-31. What is the hydroxide ion concentration in a saturated aluminum hydroxide solution?
Added by William P.
Step 1
Let x be the concentration of Al^3+ that dissolves, then the concentration of OH^- will be 3x. Now we can substitute these values into the Ksp expression: Ksp = (x) (3x)^3 Given that Ksp = 2.52 × 10^-31, we can now solve for x: 2.52 × 10^-31 = (x) (3x)^3 2.52 Show more…
