Acid base and redox titration of vitamin C Lab Report

Acid junior-grade and oxidoreduction titration of vitamin C - Lab Report guinea pig11 Moles of vitamin C 0.0031938mol Mass of vitamin C 0.564g Percent of vitamin C in the tablet 85.5% mesa 2The table below summarizes the results if the redox answer experiment Data Trial Mass tablet used 0.67g Molarity of I3- (moles/L) 0.0990mol/l Initial volume of I3- (mL) 4.1 mL Final volume of I3- (mL) 28.6 mL intensity of I3- used 24.5 ml Moles of I3- used 0.0024mol Vitamin C base molar ratio 11 Moles of vitamin C 0.0024mol Mass of vitamin C 0.43 g Percent of vitamin C in the tablet 64.18 % The equations used to find the answers in the trials are written bellow, Equation for table 1 C6H8O6(aq) + NaOH(aq) - H2O(l) + Na+(aq) + C6H7O6-(aq) Equation for table 2 C6H8O6(aq) + I3-(aq) - 3 I-(aq) +C6H6O6(aq) + 2H+(aq) Discussion/ConclusionChemical properties of substances initiate answers. The reduction seat of vitamin C, for example, is responsible for the chemics property to initiate reactions with other chemicals. The unpleasant has a high tendency to donate electrons to other chemicals forming a basin for reactions. Based on stoichiometry and known information of a chemical in reaction with vitamin C, elements much(prenominal) as the number of moles and even mass of vitamin C can be determined from a reaction that can be either an acid base reaction or a redox reaction. The acid base reaction involved sodium hydroxide solution, the base in the reaction, and vitamin C, the acid. The equation for the reaction is prone as follows C6H8O6(aq) + NaOH(aq) - H2O(l) + Na+(aq) + C6H7O6-(aq) Vitamin C was oxidized in the process while sodium hydroxide was reduced. The redox reaction is on the other hand represented by the following equation, C6H8O6(aq) + I3-(aq) - 3 I-(aq) +C6H6O6(aq) + 2H+(aq) The oxidation reaction is given(p) by the following equation C6H8O6(aq)-C6H6O6(aq)+...

The accurate titration is the acid base reaction. This is because it offers the same percentage composition as indicated on the vitamin C tablet used. The experiments offered different results. While the redox reaction yielded a percentage composition of 64.19 percent, the acid base reaction yielded 85.5 percent. The difference in the numbers could be overdue to a number of errors. The first type of error that could have led to the difference is inaccurate standard of the reactants. Such could occur in measuring readings in the titration process for the redox reactions.
