What would you do if you (or a student in your Organic lab) spilled about 150 mL of solution containing DMSO, DME, water, ~6 M HCl, iron (II) chloride and ferrocene all over your lab notebook?
I dunked it in a tub of water with sodium bicarbonate followed by a dunk in clean water. I'll let you know how it turns out. Wrinkly, I'm sure.
UPDATE: Yup, it's wrinkly. Crunchy too, but legible and perhaps usable. The pages are a little brown from the residual iron which I'm sure has settled into a +3 oxidation state.

I thought that was a trick question! Like it turns out it was just Coke or something... but I'm not a chemist, and you are, so the joke's on me!
Hope it turns out well.
I think your title should be WWVD (What Would Vogel Do) but since you have ferrocene in the mix WWJD (What Would Jolly Do).
I would have followed the bicarb with a dip in dilute bleach and then clean water and interleaf the pages with paper towel to dry. Sound like you have the makings of a good forensics lab.
Steve- Sadly, it wasn't a trick question. Just a real mess.
Liberal Arts- I didn't think of the about the dilute bleach. My main goal was to neutralize the book. I've never taken the pH of a lab notebook before. It was around 1.
That's why I use an electronic lab notebook. But if you spill on it...nevermind.
Ya know, Dr. Kev, I have in my office (somewhere) a few notebooks from 1988-1990 that were left behind by my predecessor. They make for good reading. Hopefully, our electronic data will be as readily available in 20 years.
This is why my notebooks stay on my desk.
And, if that happened to my notebook, I'd just call Jeff down to dispose of it. And then write up a minor incident report. And then play Sporcle for the rest of the afternoon.
If that happened with my students, I would first congratulate them for having the ability to make a chemical compound that did not involve rock cocaine and baking soda.
Then, I would totally freak out!!! I'm old school. Lesson plans and notes are all hand written in my note books ~ school districts do not give technology to the programs that teach/babysit juvenile delinquents.
Good to see that you were able to save the pages.
1% hydrogen fluoride or 5% KHF2 or ammonium difluoride solution is great for removing rust stains. (But it is quite toxic on skin and corrosive on glass surfaces.) Alternatively you could use EDTA solution but difluoride is better. To remove ferrocene stains I would use hexane, it should not dissolve the ink. The best way to recover wet notebook (a typical problem when lab gets flooded), the best way is to freeze it immediately in freezer and then dry it by lyophilization, there are even companies that do this professionally as a book recovery service. Do not try to pry the wet pages apart, it will most likely tear and mush them
Spilling laboratory substances is very dangerous. When this happened in the admiral Farragut academy employment and all the laboratory assistants, professors and students were very scared. Because they did not know how to act in such situations. Now they have an algorithm of actions known to all professionals, laboratory assistants, and students, so they know how to act if this happens and no one is afraid of what is happening.
Great blog! Is your theme custom made or did you download it from somewhere?
A theme like yours with a few simple tweeks would really make my
blog stand out. Please let me know where you goot your theme.
Kudos
I think that every student hasn't so much money to buy a new laptop. If I had problems with my laptop I would cry) If there was such an excellent article https://www.iiste.org/tag/domyessay/ written by be on laptop I would cry more.
If I had important notes in my notebook I would worry. Now i have only important note in my notebook is a note that I have to read an excellent article about essay writing service because I need an essay writing service but don't know which I have to order!
It is excellent that I haven't such problems because I have a very important note in my notebook with the link to the article with tips to writing a unique essay fast which I have to read because I can't write such an essay quickly and I want to study how to do it.
I always visit your blog to read insightful articles such as this. Good work.
I would have followed the bicarb with a dip in dilute bleach and then clean water and interleaf the pages with paper towel to dry.
