An unknown cadmium(II) solution was analyzed. A 25.00-mL sample of the unknown solution produced a diffusion current of 1.86 mA. Following addition of a 5.00-mL aliquot of 0.00212 M Cd2+ standard solution to the unknown solution, a diffusion current of 5.27 mA was produced. A) What type of electroanalytical method was used? B) What type of calibration method was used? C) What is the molar concentration of Cd2+ in the unknown solution?
