Redox Reactions
Summary: Provides the details on a experiment on redox reactions. Attempts to predict a number or redox reactions from a table or relative reactivities of some common oxidants and reductants, and then to check these predictions by experiment.
To predict a number of redox reactions from a table of relative reactivities of some common oxidants and reductants, and then to check these predictions by experiment.
APPARATUS
The following materials are required in order to complete this experiment:
,,X Reaction palette or set of semi-micro test tubes and stand
,,X Clean plastic tray
,,X Latex gloves
,,X Goggles
,,X Set of small dropper bottles containing each of the following:
fæ Freshly prepared FeSO4
fæ 0.1M FeCl3 solution
fæ 1M sulfuric acid, H2SO4
fæ 0.1M H2O2 solution
fæ 0.1M KSCN solution
fæ 0.1M K3Fe(CN)6
fæ Freshly prepared 0.1M KI solution
fæ 0.1M sulfurous acid solution, H2SO3
fæ 0.1M K2Cr2O7
fæ Freshly prepared starch solution.
PROCEDURE
- Add 10 drops of hydrogen peroxide solution to one test tube or to the palette, then a few drops of sulfuric acid. Then slowly add a few...
