# Problem: 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 X 10 -4 M and the measured cell potential is 1.82 V. Calculate the Ksp value for Al(OH)3.Al(OH)3 (s) ⇌ Al 3+(aq) + 3OH -(aq)       K sp = ?
