So I wanted to prepare an experiment for chemistry. I got a few things, for example methanol. Of course, I looked at the protective measures, so the question is, can you keep the fumes away with an FFP2 mask (I also have eye protection).

Loading...Hello, I still had some disinfectant (99% ethanol) lying around. When I opened the box When I unpacked it, there were greasy, white deposits on the edge. What is that? Is it saponification? If so, with what? Besides ethanol, there's nothing else in it. The bottles were wrapped in plastic film.
I came across the self-cooling CoolKeg beer keg and find the technology behind it very exciting. However, I have a question about the liquid water used as the cooling medium. Why is water used and not another liquid with a higher vapor pressure, such as ethanol? Higher vapor pressure increases evaporation and thus also the…
Hello, why is a nitrate ion simply negatively charged, or why is this even possible when the three oxygen atoms can take up six electrons and the one nitrogen atom can only give off five electrons (NO_3). Shouldn't it balance this out overall? There are six electrons that can be absorbed and five that can…
Thanks in advance. I don't know if those are correct. (They're not mine.)
Such as 2H2+O2–> 2 H2O only the OZs change How do you then write the partial equations? like this: O2 + 4 e—> 2 O2- 2H2–> 4H+ + 4e The electrons are not transferred?!
No, these masks protect against particulate substances only by their filter functions. Gases and thus also methanol, which is in the gaseous state by evaporation, are not held by these masks.
No special precautions are required when working with methanol. You shouldn’t drink it.
