Three sequential reactions are occurring in Step 2.
Assuming that each reaction produces the zinc (II) ion (Zn2+),
write a balanced redox reaction for the yellow to blue transition
(assuming acidic conditions). You can ignore the NH4+ and SO42-
spectator ions. Remember to add H+ ions to balance the charge in an
acidic solution if necessary.

Procedure Separation and Identification of Pb2 (aq), Fe (aq), Al(a), and Cu Note: Tests should be performed concurrently on the known and the unknown solutions. Volumes are approximate. All work excepting the centrifugation should be done in the fume hood 1. To about 2. mL of your sample in a test tube, add 5 drops (-0.2 mL) of 6 M HCl(a). Mix well and centrifuge. Decant the clear liquid into a clean test tube and save it for Step...

Introduction Titration is a common analytical technique that is used to verify the concentrations of chemicals before they are sold as commercial products, in a process known as quality control. In this lab, you will be using a redox titration to find the concentration of the strong oxidizing agent hypochlorite (CIO) which is the active ingredient in bleach. Oxidizing and reducing agents are often determined using a redox titration....
