Question

9.24 An aqueous solution containing 15% NaOH and 0.5% NaCl is concentrated at a rate of 100 kg/min in an evaporator. The concentrated solution is then mixed with 2000 kg of aqueous NaOH solution in a mixer. At the end of one hour a sample is collected from the mixer and analyzed. The analysis shows 40% NaOH and 0.8574% NaCl. Calculate the following: (a) The concentration of the original solution in the receiver (b) The composition of the concentrate from the evaporator (c) The mass of water in kilograms) evaporated in one hour​
