dissolved and diluted to 300 mL with water. A 20 mL aliquot was A 15.00 g sample containing mixed alkali and other inert components titrated with 5.02 mL of 0.5352 M HCI to reach PHP endpoint. Another 20 mL aliquot was titrated to the BCG endpoint, using up 18.87 mL of titrant in the process. What is/are the component/s of the sample? O NAOH only O NaHCO, only O NazCO, only O NAOH and NazCO3 O NaHCO, and Na CO3

The percentage purity of a paracetamol sample was determined by a reversed phase HPLC method as follows: • A calibration curve of peak area versus concentration (ug/mL) of pure paracetamol was constructed The paracetamol sample for analysis was prepared by taking 10.0254 g of powder and dissolving it in IL of distilled water (solution A). 1 mL of the latter solution was further diluted to 1L with distilled water (solution B). Solution B was analysed by HPLC analysis Results • The equation for the best-fit line of the calibration curve is: y = 26811x – 1313.8 The average peak area for the paracetamol sample (solution B) was 266796.2 Calculate the percentage purity of the paracetamol powder.
