Good morning,
I'm researching how a catalyst works. I also know that various acids can serve as catalysts. But I can't find a proton transfer process using a catalyst. Is that even possible? Does anyone have an example?

Loading...Hi, I have to write a protocol about an experiment with Petri dishes. Does anyone have experience with this or have ever written a report about it?
Hello dear chemists, In class, we're studying redox reactions in relation to oxidation numbers. We're taught how to set up an equation, but not the underlying principles. Regarding my example question: Hydrogen peroxide (H2O2) is reduced to water (H2O). The electronegativity of oxygen changes from -I to -II as it gains an electron. So far,…
Titanium as a raw material for luxury pans? What do you think about that idea? Nothing rusts. Or titanium steel?
What is the formula of C3H6O3? Thanks 🙂
Reactant that releases O² = oxidizing agent Reactions in which O² is absorbed are called oxidation
Protonenübertragungen selbst laufen so razzfazz ab, da kannst und brauchst du nichts beschleunigen. Die Katalyse durch Säuren funktioniert dadurch, dass eben nicht ein Molekül reagiert, sondern das protonierte Molekülion. Also z.B. reagiert Essigsäure schlecht, das Ion CH₃-C(OH)₂⁺ sehr wohl.
Geschwindigkeitsbestimmend ist die Konzentration des CH₃-C(OH)₂⁺ und wie schnell es dann reagiert, nicht die Geschwindigkeit der Protonierung der Essigsäure.
