Quicklime: Properties & Uses for Drying Gases

[Fly_High]

Quicklime is used to dry gases.It is also basic in nature. It cannot be used to dry acidic gases such as sulphur dioxide and carbon dioxide.

Why is this so? Is it because alkali (quicklime) will react with the acidic gases to form salt and water?

Please help. Thanks.

You have answered your own question. Sulfur dioxide and quicklime will react to make calcium sulfate, CO2 also reacts.
