Question

When sodium carbonate is heated show the reaction occuring at the same time.​

Answer 1

Answer:

Explanation:

Sodium bicarbonate is regenerated to sodium carbonate when heated.

Because the reaction between sodium carbonate and carbon dioxide and water is highly exothermic, the particle surface where the reaction occurs may be much hotter than the bulk gas temperature.

Answer 2

Answer:

What is the reaction of sodium carbonate when heated?

Anhydrous sodium carbonate is very unlikely to undergo decomposition, so for most purposes, the correct answer is “no reaction”. For example,

…as opposed to most of the other group (I) carbonates, which decompose very slowly above their melting point and only significantly decompose above their boiling point , impractical in the lab. For example, careful measurement of the thermodynamics of the reaction predict a shift in equliibrium toward decomposition of sodium carbonate in excess of 2400K . (from )

At extreme temperatures, it might decompose in a number of ways. In the presence of other reactive materials, including water, other reactions are possible, though, and depend on the mix of partial pressures of carbon dioxide and water as well as any other reactive gases. Most sodium carbonate exists as a combination of its hydrate as well as various mixed compounds of sodium carbonate and sodium bicarbonate, as naturally found in and other sodium carbonate containing minerals. Heating the hydrate is likely to release water and form the carbonate anhydride.
