Question

Air contaminated with SO, and NO2 can be cleaned by bubbling air through a suspension of Mg(OH)2 in water. The following two reactions occur in the suspension: Q1. Excess Mg(OH)2 removes all the SO2 and NO2 from the air. The magnesium solids decompose upon heating as follows Mgso,-) Mg0 + SO2 (at 200°C) O2+Mg(NOMgO+2NO, (at 250 °C) Mg(OH) MgO+HO (at 350 °C) The second reaction above uses excess oxygen. Mg(OH2 can be regenerated by the following reaction: MgO +H OMg(OH) (at 20 °C) SO2 and NO2 are collected separately and later converted to H2SO4 and HNOs respectively Using the information table given below, design a process to produce clean air, SO2 and NO2 from air polluted with SO2 and NO2. You may use MgO, HO and air as reactants. You need not isolate pure SO2 and NO; you may produce water solutions of each SO2 and NO2

Explanation / Answer

The process of producing clean air is itself given in the question. No more explanation is required.
