1. Write the reaction equations for the quantitative determination of sodium chloride by PS. Calculate the volume of silver nitrate solution needed to titrate the pharmacopoeial sample. Calculate the correction factor for silver nitrate if 5.5 ml of a titrated approximately 0.1 mol/l silver nitrate solution was used to titrate a sample of 0.0293 g of sodium chloride. The theoretical titer of a solution of silver nitrate for sodium chloride is 0.00585 g / ml.
