(a) Identification of lime and soda for different salts

(b) Calculation of CaCO3 equivalents

(c) Calculation of lime requirements

(d) Calculation of soda requirements

The question was posed to me in an international level competition.

I'd like to ask this question from Lime Soda Process topic in division Water and its Treatment of Engineering Chemistry II

Answer 1

The correct choice is (b) Calculation of CaCO3 equivalents

The best I can explain: Calculation of CaCO3 equivalents is the second step for calculating the amount of lime and soda. First step is to identify the lime and soda for different salts. and the last two steps are the calculation of lime and soda requirements.
