Sodium hydroxide is usually produced from common salt by electrolysis. The basic elements of the system are shown in the following flowchart. All percent compositions are mass percent. a) What is the percent conversion of salt to sodium hydroxide b) How much chlorine gas is produced per pound of product c) How much water must be evaporated at the evaporator per pound of product Note: The composition are mass percent (convert from mass fraction to mole fraction) Basis 100 kg of product stream . You may use atomic species balance for Na, Cl, H, and O Cl H HO Salt 30% Product Dissolver HO Solution Electrolysis System Evaporator 50% NaOH 7% NaCl 43% HO Sodium hydroxide is usually produced from common salt by electrolysis.
