2016年4月6日 · In this Wikipedia article, it mentions: As the concentration of sodium carbonate increases, it undergoes hydrolysis to form sodium hydroxide. $$\\ce{Na2CO3 + H2O → 2NaOH + CO2}$$ Because this

2013年5月28日 · The solvation of sodium carbonate is an exothermic process, so the process would raise the temperature of the solution, but I doubt that's sufficient to explain the unexpectedly great solubility that you observed.

2017年5月9日 · Why is sodium carbonate less soluble in water than sodium bicarbonate? If you think about their structures, the only thing that is different is that sodium carbonate has two sodium atoms, while sodium bicarbonate has one sodium atom and one hydrogen atom instead of the second sodium atom.

2014年2月14日 · The question should be more specific asking for the ultimate products of the reaction because all these are products of the dissociation of sodium hydrogen carbonate and because are equilibria is probable that all the species are present in different amounts when the reaction reach the equilibrium.

2023年5月13日 · The webpage explains why sodium hydrogen carbonate decomposes into sodium carbonate, water vapor, and carbon dioxide.

2023年2月9日 · I wanted an explanation why the sodium bicarbonate (NaHCOX3 N a H C O X 3) decomposed into sodium carbonate (NaX2COX3 N a X 2 C O X 3), water (HX2O H X 2 O), and carbon dioxide (COX2 C O X 2); and didn’t just turn to sodium bicarbonate in its gas form, since its boiling point is 333.6 °C.

2019年7月14日 · Sodium carbonate is used in pools to raise pH. From my understanding, it would dissociate in water like so:

2020年10月27日 · At a small scale I have been using Sodium Carbonate (Na2CO3) and it has worked fine, however I intend to scale it up to ~1m^2 plates for the Anode and Cathode, as well as 150A @ 15v DC for ~3min in Deionised water with many repeats, so temperature rise of the water should also be accounted for.

2024年7月7日 · So, yes it is a temporary solution to address water hardness. I recommend relatedly to hard water treatment with Washing Soda, a very interesting experiment of adding Na2CO3 (aq) to MgSO4 (aq) as the entire solution, at times (it depends on respective concentrations), can convert to a wet hydrate creating so-called Magnesium alba.

2014年10月5日 · This answer goes into lots of detail, but it seems to focus on why calcium carbonate won't dissolve in the first place. (Which, to be fair, was the focus of the original question.) What about: Why does calcium carbonate precipitate out when you dissolve calcium chloride and sodium carbonate in water?
