Consider the standard cell at 25 degrees Celsius based on the following half reactions. Pb^(2+) + 2e- > Pb Eofcell = -0.13V Zn^(2+) + 2e- > Zn Eofcell = -0.76V To the STANDARD CELL, OH-, is added to the zinc compartment causing precipitation of Zn(OH)2. After precipitation is complete, the concentration of the OH- is -0.10M and the measured cell potential is 1.05V. Calculate the Ksp value for Zn(OH)2(s). Zn(OH)2 > Zn^(2+)(aq) + 2OH-(aq) Ksp = ? PLEASE show ALL work, I rate ALL 5 stars.
