WebFurthermore, it promoted healing of infected diabetic wounds due to a synergistic antibacterial effect providing the dynamic exchange between Fe 3+ ions and gentamicin. This work provides a strategy for the design of dual-function wound dressings, with both starving and killing bacteria and enhanced wound healing performance. WebIk what to do after u get the 1:6 ratio But what I don’t get is in the mark scheme it doesn’t explain why Fe 2+ is oxidised to Fe 3+. Like why does Fe 2+ specifically lose 1 electron in this reaction and how am I supposed to know . And why is cr2o7 2-reduced to cr 3+, like is that the case for every reaction involving dichromate ions, that u always have to assume …
