The diffusion current in a polarogram for reduction of Cd2+at a mercury electrode is 12.0 mA. If the solution contains 19.5 mL of 0.50 moldm-3 Cd2+, what percentage of Cd2+ is reduced in 2.5 minutes required to scan from -0.6 to -1.2 V? comment.
In an analysis of chromium in steel containing 1.76% Cr. 0.5000 g of that steel is weighed and dissolved in acid, whereupon the Cr is oxidized to Cr2O72- (dichromate), and blunt to a volume of 250 mL. A 10 mL aliquot of this solution is diluted with water and acid to a final volume of 100 mL. The resulting solution shows a transmittance of 41.7% in a 1 cm pathlength cell. When a 0.7500 g sample of unknown steel is dissolved in acid, oxidized, and diluted to 250 mL, the resulting solution exhibits a transmittance of 61.3% under identical experimental conditions. What is the percentage of Cr in the steel?
