carbonate ions migrate across the anion-exchange connector and combine with H+ions produced at the anode through the oxidation of water to form a carbonic acid solution. The potassium hydroxide solution reacts with the carbonic acid solution to form potassium carbonate (K2CO3) solution, which can...
Its reaction equation is: K2CO3 + CO2 + H2O → 2KHCO3 Ion exchange method: The potassium chloride solution is countercurrent passed through the ion exchange column after removing calcium and magnesium, making the (R-Na) be converted into potassium type (RK). Wash with soft water to remove...

Air & Water Reactions Addition of water to hydrosulfide may drop the pH and allow copious quantities of hydrogen sulfide to be produced. Acid accelerates the H2S production. Reactivity Profile Inorganic sulfides are generally basic and therefore incompatible with acids. Many of these compounds are red...
