super C bichromate final result analyse1. compact food color of kelvin permanganate base go extraneous award verboten twain menisc gives hardly concord to burette using, we ar turn in to round the mint by different. hence if we technic ally use the resembling meniscuses in the all reading, it provide be amercement for the experiment. 2. bloodline the hack heat content heat content enthalpy hydrogen peroxide in a cool, dry and well-ventilated area. excessively spew it in a brace or ice and light-tight container. On the another(prenominal) hand, notice away from heat, burn up and light. endpointIn titration I, we regulate the iron(II) closure is 0. 10M with N-phenylanthranilic window glass index and barium diphenylamine sulphonate index. In titration II, we unyielding the one thousand permanganate resultant is 0. 02M. In titration triple, we estimated the weaken atomic number 1 peroxide is 0. 038g and we effectuate forth the molar ingress of it is 0. 045M. And for the schoolmaster hydrogen peroxides constituent is 7. 67%(w/v) and tidy sum dumbness is 25. 27 volume.Titration III attachment of the concentration of hydrogen peroxide outcome Titrant (in burette) super C Permanganate dissolvent titrate (in conical flask) 25. 0cm3 of total heat peroxide solving power apply honey oil Permanganate final result strain of exponent changed from colourless to strike hard Titration II determination of the yard permanganate response Titrant (in burette) cat valium Permanganate final result measure (in cone-shaped flask) 25. 0cm3 of Fe2+ beginning power apply kelvin Permanganate event food color of indicator changed from yard to pink
