You want to determine the % of an acetic acid sample solution by acid/base titration. Therefore, you prepare a NaOH solution. To determine the exact concentration of this NaOH you titrate exactly 390.3 mg KHPhthalate (M = 204.22 g/mol) with this NaOH solution requiring 8.2 ml. Subsequently you use this NaOH solution to titrate 25.0 ml of your acetic acid sample (M(acetic acid)=60.05 g/mol, density of solution 1 g/ml) resulting in a consumption of 6.9 ml of the NaOH solution. = Please give all relevant reaction equations (with correct stoichiometry). Calculate the exact concentration (in mol/L) of the NaOH solution. Please calculate the weight-% of acetic acid in the sample solution. Which indicator would you use for this titration/at which pH range would you expect the equivalence point? (8)
