1- A sample weighing 1 g contains acetic acid (FW = 60 g/mol). The content of acetic acid in the sample was titrated with NaOH (FW = 40 g/mol) 0.05 M and the volume required to reach the equivalence point was 23 mL. Calculate the weight percent of acetic acid in the sample. 2- Calculate the pH of a solution prepared by mixing 50 mL HCI 0.15 M 100 s mL NaOH 0.05 M. 3- In the titration of 20 mL CH;COOH (K, = 1.76 x 10*) 0.4 M with a solution of NaOH 0.4 M, calculate the pH of the resulting solution after addition of: a- 0 mL NaOH b- 10 mL NaOH c- 20 mL NaOH d- 30 mL NAOH
