A certain half-reaction has a standard reduction potential -1.33V . An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 0.70V of electrical power. The cell will operate under standard conditions. a. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have?b. Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have?

Which statement is true about ionic compounds?

Salicylic acid is a very important acid. it is used to synthesize the aspirin by treating with acetic anhydride. a 0.2015-g sample of salicylic acid was dissolved in a 100.00-ml volumetric flask, and the solution was diluted to the mark. a 10-ml aliquot of this solution was titrated with standard naoh (0.01130 + 0.2% n) to a phenolphthalein faint pink color end point at 19.81 ml. (a) (calculate the normality of the salicylic acid solution used in the titration. (b) assuming the salicylic acid is pure, what is the equivalent weight of the salicylic acid? practice problems for the final exam (continued) (c) (calculate the inherent error in the determination of the equivalent weight you calculated in part (b). use the following absolute errors in the equipment /glassware when calculating the inherent error. 5.00-ml pipet: + 0.02 ml 100-ml volumetric flask: + 0.08 ml analytical balance: + 0.2 mg 25-ml buret: + 0.03 ml
