The discussion centers on how to accurately count chelate rings in the complex [Co(EDTA)]-. Participants express uncertainty about the definition of chelate rings and suggest visualizing the structure to identify them. One contributor notes the presence of five linkages in their diagram, implying that this might indicate the number of rings. The conversation highlights the need for clarity in defining the start and end points for counting. Ultimately, visual representation is emphasized as a useful method for understanding chelation in coordination complexes.

TL;DR: What are the five chelate rings in [Co(EDTA)]-

Since I can't find a definition I just drew cycles.

When to start and end?

Well, I see five purple linkages in the diagram, so maybe that gives you a hint...

Thread 'Molecular-level explanation of macroscopic phenomena: dissolving'

What I know and please correct me: a macroscopic probe of raw sugar you can buy from the store can be modeled to be an almost perfect cube of a size of 0.7 up to 1 mm. Let's assume it was really pure, nothing else but a conglomerate of H12C22O11 molecules stacked one over another in layers with van de Waals (?) "forces" keeping them together in a macroscopic state at a temperature of let's say 20 degrees Celsius. Then I use 100 such tiny pieces to throw them in 20 deg water. I stir the...
