Provide basis, find, Process flow diagram and show step-by-step solution for the process. Topic: Material Balance with multiple units An aqueous solution containing 30mol% NaCl is used to produce NaOH by electrolysis. At the anode, the chloride ion is oxidized to chlorine gas; at the cathode, water is reduced to hydroxide and hydrogen gas. The chlorine gas and hydrogen gas exit the electrolysis system while the remaining solution is concentrated in an evaporator to produce a product containing 50mol% NaOH, 7mol% NaCl, and 43mol% H2O. a. What is the percent conversion of salt to sodium hydroxide? b. How much chlorine gas (in kg) is produced per kg of the product? c. How much water (in kg) must be evaporated in the evaporator per kg of the product?

Question
Provide basis, find, Process flow diagram and show step-by-step solution for the process.
Topic: Material Balance with multiple units
An aqueous solution containing 30mol% NaCl is used to produce NaOH by electrolysis. At the anode, the chloride ion is oxidized to chlorine gas; at the cathode, water is reduced to hydroxide and hydrogen gas. The chlorine gas and hydrogen gas exit the electrolysis system while the remaining solution is concentrated in an evaporator to produce a product containing 50mol% NaOH, 7mol% NaCl, and 43mol% H2O.
a. What is the percent conversion of salt to sodium hydroxide?
b. How much chlorine gas (in kg) is produced per kg of the product?
c. How much water (in kg) must be evaporated in the evaporator per kg of the product?
