Question

In the Le Blanc Soda Process the first step is carried out according to the following reaction:

NaCI + H2SO4 = NaCI + NaHSO4 + HCI

The acid contains 80% H2SO4. It is supplied 5% in excess of that theoretically required by the above reaction.

(a) Calculate the weight of the acid supplied/1000 kg salt charged
(b) Assume the reaction goes to completion, and that in the process 90% of the HCI formed and 25% of the water present are removed, calculate the weights of HCI and water removed per 1000 kg of salt charged.
(c) Assuming conditions of (b), calculate the % composition of the remaining salt mixture.
