Acidic MnO4- solution reacts with ethanol, CH3CH2OH, to produce acetic acid, CH3COOH.

a. Give a balanced equation for the reaction. 

b. What volume of 0.200 M MnO4- solution is needed to titrate 22.5 mL of a 0.350 M solution of ethanol?

A concentration cell has a standard Zn2+cathode (1 M Zn(NO3)2/ Zn electrode) and a saturated (Zn(OH)2/ Zn electrode) anode. The cell potential is measured to be 0.169 V.

a. Write the two half-reactions, labelling all species with their corresponding states (aq, s) and electrode (cathode and anode). 

b. Determine the concentration of [Zn2+] of the anode, and the Kspof Zn(OH)2.
