The above equation illustrates the reaction between the compound Potassium bicarbonate (KHCO3) with Sulfur dioxide (SO2) and water (H2O), resulting in the formation of Potassium bisulfate (K2HSO4) and Carbon dioxide gas (CO2).
- Reaction Conditions
This reaction occurs at normal temperature, without the need for pressure or specific temperature conditions.
- Reaction Process
During the reaction process, the bicarbonate ion in Potassium bicarbonate reacts with SO2 and H2O, forming a sulfite and then further transforming into bisulfate, simultaneously producing CO2 gas. This is a reduction-oxidation reaction, in which SO2 is reduced to bisulfate and bicarbonate is oxidized to CO2.
- Observable Phenomena
The most notable phenomenon during the reaction is the release of CO2 gas. This is a colorless, odorless gas with the ability to rendering lime water turbid.
