The reference technology to be used as the basis for improvementis
that now employed by AEP in Conesville,Ohio, and by CG&E at the East Bend Station located on the Ohio River south of Cincinnati. The process is also to be utilized at the W.H. Zimmer Station in Moscow, Ohio. A schematic flow sheet of the process is shown in Figure 2-3. Flue gas, after particulate
removal, is now passed counter-currentto a flow of slurried lime in a
scrubbingtower. The lime slurry is injected into this system by a serics of
spray headers at the top of the tower and collected in a recycle tank at the
base of the tower. Slurry from the recycle tank is continuouslywithdrawn
and returned to the spray headers by suitable pumps. A relatively small
purge stream is withdrawn from the recycle tank and pumped to a thickener for
partial dewatering and then to a vacuum filter for final dewatering. Makeup
slurry is added to the reactortank as needed. The wet solids from the
vacuum filter are mixed with fly ash, often with a little extra lime as weil,
to obtain a composition that will harden with aging, and then trucked to a
dedicated landfill. This technology and the similar limestone scrubbing
process are the principallyused methods for treating the flue gas from the
combustion of high-sulfurcoal in the U.S.

well when you mix CaO and SO2 u get CaSO3
CaO (solid) + SO2 (gas) → CaSO3

Just so u know result is not that soluable in water, but since the reaction will happen u get the calcium sulfite solution

The website below is a lab report done by someone else, but it basically s...

The website below is a lab report done by someone else, but it basically states that the above reaction will take place. The purpose of the question is basically asking if the reaction will occur or not.

The Ksp of calcium sulfite is 6.8 x 10^-8, so it is only slightly soluble. Although it is possible to dissolve some CaSO3 in water, it would most likely result in a slurry rather than a solution.

Because the solubility of CaSO3 (calcium sulfite) is so low, it can only be referred to as a semi-electrolyte. Semi-electrolytes are much much nearer to the non-soluble end of the electrolyte spectrum. This means that only a miniscule number of particles of CaSO3 in the mixture will be dissolved. Ergo, the reaction of solid CaO and gaseous SO2:

CaOs + SO2g ---> CaSO3 (?)

This will result in a mixture that is almost entirely a slurry, although a negligible amount of the CaSO3 will have dissolved. Therefore, your answer should be that it will result in a slurry.

CaO(Solid) + H2O(liquid) + SO2(gas) -> HCaSO5(aquis)

the final froduct would be in the aquis stage. the equastion explains itself
