In the LeBlanc side process, the first step is carried out according to the following reaction :
2NaCl + H2SO4 ==>> NaCl + NaHSO4 + HCl

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

a) Calculate the weight of acid supplied per 1000 kg of salt charged
b) Assume that the reaction goes to completion, all the acid formed , and 25% of H2O present are removed.Calculate the weights of HCl and water removed per 1000kg of salt charged
c) Assuming the condition of part b, Calculate the % composition of the remaining salt mixture.
