Determination of Iron by Reaction with Permanganate-A Redox Titration

Determination of Iron by Reaction with Permanganate-A Redox Titration Purpose: The purpose of this experiment was to find the percentage of iron in an unknown iron oxide sample which could be determined through titration with a standard solution of potassium permanganate. Success in this analysis requires careful preparation and attention to detail. Performing this experiment also provides practice at titrations. The overall reaction is: 8H+(aq) + MnO4-(aq) + 5e-  Mn2+(aq) + 4H2O Theory:...

Potassium Permanganate

5. POTASSIUM PERMANGANATE Potassium permanganate (KMnO4) is used primarily to control taste and odors, remove color, control biological growth in treatment plants, and remove iron and manganese. In a secondary role, potassium permanganate may be useful in controlling the formation of THMs and other DBPs by oxidizing precursors and reducing the demand for other disinfectants (Hazen and Sawyer, 1992). The mechanism of reduced DBPs may be as simple as moving the point of chlorine application further...

Aromatic hydrocarbons are cyclic compounds whose structure is related to that of benzene, with six -electrons in a six-member ring. Aliphatic Hydrocarbons such as Alkanes are relatively inert to chemical oxidizing agents such as neutral or alkaline permanganate, where alkenes are readily oxidized at room temperature. The change in color can be used as a test for a double bond, provided the molecule contains no easily oxidizable group. Aromatic Hydrocarbons such as toluene will be used in each of the...

Manganese Experiment

to the metal to form a six-membered chelate ring. In some cases the chelate effect is so strong that no added base is needed to form the complex. (wilkmson,1995) In this experiment a solution of manganese (II) chloride is oxidized with potassium permanganate in the presence of acetylacetone giving the brown acetylacetonemanganese (III), Mn (acac)3. Because the ground state for octahedral complexes like that of Mn(acac)3 is a 5Eg (t2g3eg1) there exists considerable Jahn-Teller distortion. Therefore...

Analyzing a Hydrogen Peroxide Solution

hydrogen peroxide in a consumer product? Design: An acidic solution of primary standard, iron (II) ammonium sulfate-water (1/6), is prepared and the potassium permanganate standard. A 25.0 mL sample of a consumer solution of hydrogen peroxide is diluted to 1.00 L with water (that is, it is diluted by a factor of 40). The standardized potassium permanganate solution is used to titrate the diluted and acidified hydrogen peroxide. The amount concentration of the original hydrogen peroxide is obtained by...

Oxidation

ketone with household bleach. The product is then isolated by steam distillation and is extracted into the distillate with ether. After the removal of ether, it leaves the product cyclohexanone. In experiment 6, cyclohexanone is oxidized by potassium permanganate. Manganese dioxide is filtered off and the filtrate is concentrated, acidified with hydrochloric acid and then cooled to yield crystalline adipic acid. OBJECTIVE: Experiment 4: To recover cyclohexanone from the oxidation of cyclohexanol...

THE EFFECTS OF MOLECULAR WEIGHT ON THE RATE OF DIFFUSION OF SUBSTANCES

of the tube containing HCL with a large molecular weight. In agar-water gel test, using agar plate and agar-water gel, 2 different substrate were tested- potassium permanganate (KMnO4) and methylene blue (C16H18N3SCl). By dropping it on a agar plate, methylene blue has a slowest diffusion rate and large molecular weight than potassium permanganate. Thus, the greater the molecular weight, lesser the rate of diffusion. INTRODUCTION Diffusion is a passive transport. It is results from...

components. * To standardize potassium permanganate solution KMNO4, which then be used for titration of iron unknown solution. * To write the net ionic equations of redox reaction carried out in this experiment. * Concept of experiments: * A standard KMNO4 solution, used in this experiment as titrant, cannot be prepared directly by dissolving of a known amount of solid KMNO4 because this reagent is a very strong oxidizing agent. Solutions of potassium permanganate are unstable and their concentration...
