Question

4.0 Lime (CaO) is one of the most abundantly produced chemicals in the world.Write balanced equations for the following reactions:

a) Preparation of Lime from Calcium Carbonate

CaCO3(s) --->

Ca(OH)2(s) + SO2(g) --->

c) Reaction of Lime with Arsenic Acid (H3ASO4) to for Calcium Arsenate (Insecticide)

3CaO(s) + 2H3AsO4(aq) --->

d) Regeneration of NaOH by reaction of Lime with aqueous Sodium Carbonate

Na2CO3(aq) + CaO(s) + H2O(l) --->

Explanation / Answer

CaCO3 ----> CaO + CO2 Ca(OH)2 + SO2 -----> Ca SO3 + H20 Na2CO3 + CaO + H2 o ---------> CaCO3 + 2 NaOH
