Extracted text: Commercial hydrochloric acid and sodium sulfate are produced by the reaction: NaCI + H20 + SO3= Na,SO4 + HCI The reaction is carried at 482°C. After separation of the Na,SO4, the HCI is to be absorbed in water. Per 1000 kg of sodium chloride charged, how much Na2SO4 and 87% by wt aqueous hydrochloric acid solution are obtained if the reaction goes to 90% completion? If the SO3 is supplied 20% in excess and H20, 100 % in excess of the theoretical amount, how much 98% sulfuric (SOzand H20) and fresh water should be fed to the reactor?
