neutralisation reaction between iron and potassium manganate

Extracts from this document...


Introduction Titration is a method to find out how much acid would neutralize an alkali The following equation shows the neutralisation reaction between iron and potassium manganate i will be carrying out this reaction in my experiment 5Fe2+(aq) + MnO4- (aq) + 8H+ --> 5Fe+3(aq)+Mn+2(aq) + 4H2O(l) We made the ammonium sulphate solution with the concentration of 0.05moldm3 with the volume 250cm3 To calculate the molecular mass i added up all the elements, (Fe(NH4)2 (SO4)2 6H2O), the molecular ...read more.

    If ?H 0 for a reaction is negative, energy is lost when the reaction occurs. The products are more stable than the reactants. Thus, exothermic reactions are more likely to occur than endothermic reactions. Reactions, which occur spontaneously, are often very exothermic.

    Using a 50 cm3 measuring cylinder measure out approximately 50 cm3 of distilled water (l) and pour it into the beaker, using a glass rod stir the water and solid together until the entire solid has dissolved. c. Transfer the contents of the beaker through a small funnel into a 250cm3 volumetric flask.

    This is because the reactants have more space to move around and bond together in. Also the thermometer has a bigger surface area in the solution meaning there is a better chance of the temperature being more accurate. I will use a stop clock to time the reaction and make sure I do not go over the intended reaction time.
