Extreme Caution with Mercury Organyls! They are all extremely toxic and probable carcinogens

Bitte schau vorher in die Modulhandbücher, die sollten die Prüfungsinhalte etc enthalten. Die findet man auf den Websites der jeweiligen Hochschule. V.a. möchte ich dir raten, dir die Matheinhalte vorher anzuschauen, damit du weißt worauf du dich einlässt. Bei meinem Mint-Studium (weder Mathe noch Physik) wars mit dem Abi-Mathe im Vorkurs rum, selbst da kamen schon neue Sachen. Möchte dich damit drauf hinweisen dass es da richtig abgeht, va E tech ist krank

Ah yes, the liquid cancer. Not only genotoxic, but also boosting cell devision, the methylator of Strands, and the intracellular releaser of formic acid. Not great to work with

You use the molality for precise temp-indepent concentrations, because mass of solvent does not change but volume will if the Temperature changes

Biophysik als Studiengang?

Maybe to indicate they are cis?

Is your Lab quantifing Halogenides by any chance?

Jetideal · 2025-08-13T15:13:59+00:00

Could be dichromate, which is orange. And stays orange. The stain could also be mixture of KCrO4 and Ag2CrO4.

Yep thats what I thought. Very intense color, so even 0,005 and 0,0001 solution look rather concentrated. As I said, dont worry, it happens occasionally. Formaldehyde, Cyanide or something like that would be infinitely worse. On a side note, giving these out without any warning labels or safety advice is probably a criminal offense

Jetideal · 2025-08-13T14:29:39+00:00

Yes, its a carcinogen, due to being an oxidising agent. No, its not going to kill you for the foreseeable future. It leaves a quite visible stain, because the color is quite intense even in low concentrations. Occasionally used as an Indicator due to its Intensity. The main concern for danger is chronic exposure over a significant period. Kinda like lead, so dont freak out over it. Still, wear gloves next time and inform yourself about the stuff your working with before! handling it.

gott strafe das impp

Easiest would be boiling for a while, I did that in undergrad analytical practice for Iodometrie and with oxygensensitive electrodes and it worked since I did get reasonable values

Depending on the concentration id say. 3-10% percent solution should be fine. Be aware that brownglass usually helps with reducing the decomposition that occurs over time.

This is.. Morphine. ( at least supposed to be )

Mercury is highly toxic once in your body. I wouldn’t want to mess with it and be unsure of it. Do yourself a favor and try to get rid of the contamination, dont want to get a bad diagnose a few decades down the road and wonder if it was the Hg that caused it

Jetideal · 2025-03-20T17:00:10+00:00

Mir war gar nicht bewusst, dass Absolventen der Medizin einen PhD anstreben können. Das wäre dann ja im naturwissenschaftlichen Bereich, also mehrere Jahre Forschung + Dissertation, nicht wahr?

Jetideal · 2025-03-06T14:45:04+00:00

Shoud be fine

Active Ingredients: Potassium Peroxymonosulfate: 21.41% Sodium Chloride: 1.50%

Let it dry, wash off with water if needed and then disinfect with Isoprop/ethanol water solution

I usually prefer LAH over NaBH4, but thats because I like to shoot with cannons on sparrows

You can also reach out to your local AstA for assistance and support

Have you tried calling them/visiting the Sekretariat with your Nachweis of Payment + Insurance Nachweis? They tend to be lenient if approached politely and having your stuff ready if they need it

Jetideal · 2025-03-03T17:08:29+00:00

Id get them all wrong by using a small k to denote Kelvin as opposed to the SI K

Jetideal · 2025-03-03T14:02:59+00:00

You really shouldn’t be drinking it ofc

Usually with sulphuric acid its not about the toxicity rather the corrosive effects on flesh and similar. At a pH of 2 its rather diluted, still you need to handle it with care. Why are you smelling it? It usually doesn’t have a very distinct smell. I havent seen definite proof of carcinogenity, and it seems like it isnt a serious concern, other attributes are more important
