The overall reaction in the lead storage battery is below

Pb(s) Pb02(s) 2 H+(aq) 2 HSO4 (a) 2 PbSO4(s) 2 H20(0)

(a) Calculate eat 25°C for this battery when [H2SO4]-3.8 M; that is, [H+]-[HS04-]一3.8 M. At 25°C,、-2.04 V for the lead storage battery.
(b) For the cell reaction HP--315.9kl and So-263.5yK. Calculate do at-24oC.
(c) Calculate eat -24°C when [H2S04]-3.8 M
(d) Based on your previous answers, why does it seem that batteries fail more often on cold days than on warm days? As the temperature decreases, the cell potential

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution. calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
