An alkaline solution of sodium carbonate made up of 0.594% NaOH, 14.88% Na2CO3 and 84.53% water is causticized by the addition of partly slaked lime. The lime contains CaCO3, CaO and Ca(OH)2. The mass obtained from the causticization has the following analysis: 13.48% CaCO3, 0.28% Ca(OH)2, 0.61% Na2CO3, 10.36% NaOH and the rest is water. The reactions are: CaO + H2O = Ca(OH)2 Na2CO3 + Ca(OH)2 = NaOH + CaCO3 On a basis of 100 kg of the causticized mass, calculate:  a) Wt and composition of the lime b) Wt of the alkaline liquor c) % excess reactant
