![]() Simply put, the entire statement above means that cleaning with washing soda, while more effective, is also riskier and more aggressive. ![]() This means that the solution becomes more strongly alkaline than is the case with baking soda. Freisinger goes on to say that a fair amount of HCO3 – and therefore, lots of OH is formed. For lay people: it’s not acidic enough – aha! So, there we have it – the acid-base behaviour mentioned before. Freisinger sends me this handwritten equation:Īccording to Freisinger, there’s no subsequent reaction to the carbonic acid here because the solution is too alkaline. An ion is a charged atom or molecule, while protons are positively charged particles. In other words, because of the instability of the carbonic acid, what’s formed is mostly carbon dioxide and water.» I briefly need to look this up. «If you mix baking soda with water, the hydrogencarbonate ions form a proton from the water and become carbonic acid. «Natron» has the chemical formula NaHCO₃, while «soda’s» is Na₂CO₃.įreisinger explains that the difference between «Natron» (baking soda) and «soda» (washing soda) lies in the acidic-base behaviour of the carbonate. «Soda», on the other hand, is called sodium carbonate (so, without the «bi» in the middle). Careful though, an English speaker’s «baking soda» and a German speaker’s «soda» are not the same thing.Ĭhemists refer to «Natron» as sodium hydrocarbonate or sodium bicarbonate. ![]() She later compares the German speaker’s «soda» with baking powder and with the product known in English-speaking countries as baking soda. The distinction is important – washing soda is the more aggressive of the two. Guide Everything you can do with baking soda (spoiler: a lot)įirst, Professor Freisinger tells me what the difference is between baking soda and washing soda.
