1.1 a) Butyric acid is to be extracted from 500 ml of an aqueous solution containing 4 g of butyric acid using ether as an extractant. The distribution coefficient of this system is 3 at 25 °C. In a minimum of ten points show that the butyric acid extracted in a single batch with 500 ml ether is less than that extracted in two batches of 250 ml portions. b) Briefly describe different strategies that can be used to obtain a chemical separation in a minimum of eight points. c) Briefly discuss ten reasons why chemical separations methods are used in analytical chemistry.
