An electrochemical cell consists of a nickel metal electrode immersed in a solution with [Ni 2+ ] = 1.0 M separated by a porous disk from an aluminum metal electrode immersed in a solution with [Al 3+ ] = 1.0 M. Sodium hydroxide is added to the aluminum compartment, causing Al(OH) 3 ( s ) to precipitate. After precipitation of Al(OH) 3 has ceased, the concentration of OH − is 1.0 × 10 −4 M and the measured cell potential is 1.82 V. Calculate the K sp value for Al(OH) 3 . Al(OH) 3 ( s ) ⇌ Al 3+ ( a q ) + 3OH − ( a q ) K sp = ?

An electrochemical cell consists of a nickel metal electrode immersed in a solution with [Ni2+] = 1.0 M separated by a porous disk from an aluminum metal electrode immersed in a solution with [Al3+] = 1.0 M. Sodium hydroxide is added to the aluminum compartment, causing Al(OH)3(s) to precipitate. After precipitation of Al(OH)3 has ceased, the concentration of OH− is 1.0 × 10−4M and the measured cell potential is 1.82 V. Calculate the Ksp value for Al(OH)3.

Definition Definition Study of chemical reactions that result in the production of electrical energy. Electrochemistry focuses particularly on how chemical energy is converted into electrical energy and vice-versa. This energy is used in various kinds of cells, batteries, and appliances. Most electrochemical reactions involve oxidation and reduction.
The sum of the numbers in the name of isA. 11; B. 13; C. 10; D. 12; E. none of the other answers iscorrect. I believe the awnser should be E to this problem but the solution to this problem is D 12. I'm honestly unsure how that's the solution. If you can please explain the steps to this type of problem and how to approach a problem like this it would be greatly appreciated!
