- A newly synthesized drug was found to have a carboxyl group, an imide and a sulfonamide group. The first type of method to consider in this drug molecule’s quantitatve analysis is: a. Non-aqueous Alkalimetryb. Non-aqueous Acidimetryc. Aqueous Alklaimetryd. Aqueous AcidimetryAn impure sample containing carbonate and sodium bicarbonate, weighing 0.5 g, was taken. It was dissolved in distilled water and then flushed with 0.1 N hydrochloric acid. If the burette reading at the end point of the phenolphthalein index is 10.5 milliliters, and at the orange methyl index end point it is equal to 30.1 milliliters. So, the percentage of sodium bicarbonate in the sample is ............., knowing that the molecular weight of sodium bicarbonate is 84 g/mol.State and describe any instrument that you will use to separate components in a mixture of amino acids containing histidine, lysine and cystein.
