701Production of chlorine gas and sodium hydroxide (caustic soda) solution

#### 701 Production of chlorine gas and sodium hydroxide (caustic soda) solution (1) The production of chlorine gas and sodium hydroxide solution (caustic soda solution (NaOH(aq))) is the chemical transformation of sodium chloride solution (NaCl(aq)) brine to chlorine (Cl2(1,g)) and sodium hydroxide solution (caustic soda solution (NaOH(aq))) that has a concentration of sodium hydroxide (NaOH) equal to or greater than 14%. (2) The production of sodium hydroxide (NaOH) must be 1:1.13 times the produced weight of chlorine (Cl2). (3) The following chemical reaction must be involved in the chemical transformation: .
