    Determine nitrogen content in lawn fertiliser using volumetric analysis

    I was attempting to calculate the amount of mol of HCl was used and then using the mol ratio from the equation, calculate how many mole of nitrogen was present. The molarity of the HCl used was 0.1M and I was supposed to multiply it by 0.003933 (as this is the average of the titres) to find the...

    Determine nitrogen content in lawn fertiliser using volumetric analysis

    Homework Statement I undertook a practical experiment where a back titration was used to determine the amount of nitrogen in fertiliser.My titres are 3.9, 3.7 and 4.2 So I know this reaction occurred: NH4+ + OH- ---> NH3 +H2O I then boiled the solution to expel the Ammonia and the excess OH-...
