    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

    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

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

    reactive than alkanes due to the presence of carbon-carbon bond. 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

    compared to HCl (dave HCl= 16.18 cm). Another experiment was performed with the use of petri dish containing an agar-water gel with three wells. 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).
