A 1.0 gram sample of impure K2CO3 is taken for analysis. The solution of the dissolved sample required 58.10 mLof 0.14 N HCl. However, 0.65 mL of NaOH was needed for back titration (1 mLof HCl is equivalent to 2.60 mL NaOH). Calculate the purity of the sample expressed as % K2O

One method for determining the purity of aspirin (C9H8O4) is to hydrolyse it with NaOH solution and then to titrate the remaining NaOH. The reaction of aspirin with NaOH is as follows:
A sample of aspirin with a mass of 1.427 g was boiled in 50.00 mL of 0.500 M NaOH. After the solution was cooled, it took 31.92 mL of 0.289 M HCl to titrate the excess NaOH. Calculate the purity of the aspirin. What indicator should be used for this titration? Why?
