3) A redox titration: 160.00 mL of 0.0500 M Sn2+ solution was titrated with 0.200 M Ce according to the reaction below. Buret containing Ce Calomel reference electrode. 0.00500 M Sn Magnetic stirring bar Titration reaction: 2 Ce++ Sn2+-------> 2 Ce3+ + Sn4+ Eº Cee-------> Ce3+ Sn+ + 2e------> Sn²+ 1.470 V 0.139 V a) What is V. (the equivalence volume) (of Ce") needed to reach the endpoint? b) Calculate the potential (voltage), when 10.00 mL Ce" is added. c) What is the cell potential at the equivalence point? d) What is the cell potential when 60 mL Ce4+ is added? SCE = +0.241 V

can you show me how to do the mechanisms and correct arrows?
