m Philadelphia University Faculty of Pharmacy Second semester 2021/2022 16/5/2022 HW #1 Instrumental Chemical Analysis Name: Student No.: Buffer in the following problem was prepared by mixing certain amounts of two solutions, solution A and solution B. Solution A was prepared by diluting 10.0 mL of concentrated Phosphoric acid (85% w/w, density 1.685 g/mL, M.wt. 98 g/mol) to 250 mL by water. Solution B was prepared by dissolving 16.0 g of NaOH (96% w/w, M.wt. 40 g/mol) in 500 ml water. (A) Calculate the pH for solution prepared by mixing 35.0 mL of solution A with 65.0 mL of solution B, and completing the volume up to 250 mL with water? (B) The claimed purity of NaOH (96%) was tested by standardizing solution B with KHP (primary standard material). 1.600 g of KHP (M.wt. 204.22 g/mol) reacted completely with 14.3 mL of solution B. Calculate the actual purity of NaOH? (C) What will be the corrected pH for solution in question (A) above? (use the corrected value of NaOH purity) (D) What volume of solution A should be mixed with 65.0 mL of solution B and diluted to 250 mL with water to prepare buffer with pH= 10.0? (use the corrected purity of NaOH) Note: • Your written answer should be delivered by hand. • Try to make your document nicely formatted. • Each student should deliver his/her work separately. • Final date to receive your work is 25/6/2022 UNIVERSITY
