mostly of sucrose with molten potassium chloride‚ a violent reaction occurs. A surprising amount of energy us released by the reactant‚ and in process‚ the atom and molecule rapidly rearrange to form 3 products(CO2/H2O and KCl). This reaction is said to be products favor. A favoured product reaction is where almost all of the reactants‚ react to form products. In this case its sucrose and potassium chlorate react completely to form carbon dioxide‚ water and potassium chloride. This reaction is exothermic

concentration of permanganate ions in the solution is inversely proportional to the percentage transmission of light through the solution. Dependent variable: concentration of permanganate ions. Independent variable: percentage transmission of light through the solution. Equipment: 20 ml of 0.00100 molL-1 potassium permanganate 20 ml distilled water 6 identical test tubes 1 Test tube rack 1 plastic pipette 10 ml measuring cylinder Photometer Method: 1.

in hospital labs to measure the glucose level in blood samples. Glucose (C6H12O6) is a monosaccharide reducing sugar. In this reaction the glucose readily donates electrons which are accepted by the permanganate causing it to change colour. The time taken for the pink colour of the potassium permanganate to disappear

will determine the Percentage Oxalate Ion (C2O42-) in our Potassium Ferric Oxalate Trihydrate (K3[Fe(C2O4)3]•3H2O) sample using a technique called Titration; a type of Volumetric Analysis. This will involve adding a Potassium Permanganate (KMnO4) solution‚ whose concentration is previously determined‚ to a solution of the Oxalate until the reaction between these species is complete. By knowing the reaction stoichiometry‚ the volume Permanganate Ion (MnO4-) solution required‚ and the concentration of

Title Experiment 17 Reaction Kinetics- Determination of the Activation Energy of the Reaction Between Oxalic Acid and Potassium Permanganate. Objective To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Theory and Background Activation energy is the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In terms of the transition-state

The agar-water gel set-up used a petri-dish of agar-water gel with three wells on it. A drop of potassium permanganate (KMnO4) was put on one well‚ a drop of potassium dichromate (K2Cr2O7) was put on the other and a drop of methylene blue was put on the third well. Methylene blue which has the heaviest molecular weight of 374 g/mole occupied a small diameter of colored area which

Objectives: * To know if potassium permanganate solution will show reactions with oil and fat samples. * To determine if the results of the performed experiment are saturated or unsaturated and alkane or alkene if the samples are mixed with potassium permanganate. Hypothesis: If the fats and oils will be added by potassium permanganate solution then we will know if it is an alkane or an alkene. Materials and Methods

One drop of each substance (potassium dichromate‚ potassium permanganate‚ and methylene blue) was placed on each respective well. In three-minute interval for 30 minutes‚ potassium permanganate‚ which has the lowest molecular weight (MW= 158 g/mol)‚ displayed the largest diameter (d= 17.5 mm) and diffused with the fastest rate (0.52 mm/min).
