@liate Mind you, the alternatives are getting steadily less attractive...J could either purchase licences for aging Windows 7 for my extra computers, or run Windows 10 (which I loathe), or throw something free on there that's going to peeve me constantly but not nearly as much as Windows 10 would.
@luke_nukem @liate I used it yesterday and still think it *smiles*
I tried preparing "Mohr's salt" or ferrous ammonium sulphate hexahydrate from horticultural ferrous sulphate and ammonium sulphate and a dash of sulphuric acid, and got clean-looking crystals, but they seemed to be about 1% deficient in ferrous iron consistently. My guess is that Mohr's salt tends to contamination by other bivalent metals that substitute freely for Fe in the "Tutton salt" crystal structure and thus cannot be readily removed by recrystallisation.
Permanganate titrations have been the easiest redox titration to get working. I've succeeded in standardizing with:
oxalic acid dihydrate (see above under alkalimetry)
potassium tetroxalate dihydrate (loc. cit.)(somewhat unsatisfactory)
potassium ferrocyanide trihydrate (prepared by reduction of photographic red prussiate of potash)
"tartar emetic", potassium antimonyl tartrate sesquihydrate (prepared from cream of tartar and pottery-store antimony trioxide)

Well, the first prototype of my handmade Delta Rune hanging is done, and tacked up behind my (temporary) altar that has nothing on it! Well, maybe now that the sigil of my patron goddess is before me at all times when I'm on my computer, I will start doing more practical witchcraft at that altar. :] https://witches.town/media/_Pd_8RuFjtULFglp-H8 https://witches.town/media/yGhzrcBVy1gZEGGUg_4
@sadie_bunny I've been sort of wanting to try a MUD or similar, but I've rather wondered what sort of crowd they attract these days...
@mawr @kara_dreamer @Cascadiarch I've been debating whether to carry out some of these sessions in other places. On the "Cuddle Pit" Discord I have a small audience of friends, but I've felt there'd be some value to doing such RPs with more eyes present, particularly fellow witches and fellow writers. I've considered using Mastodon for the purpose
@mawr After I get back from my shopping trip I wish to corral @kara_dreamer's wandering attention into some ritual work on @Cascadiarch's Discord server. We have set up a virtual island for the purpose but have made scant use of it lately.

Good morning Awoo (and Mastofediverseosphere)!
What's one thing you want to get done today? Tell me about it and we can keep each other on track! :D
My one thing: I wanna convert a bunch of code from one project to another for work by the end of the day.
Nya-ing
@BigFatFae @Ulfra_Wolfe Oh, how cute! *joins the katamari session*
@BigFatFae Hello, Krissy! *bows*
@blackle@dev.glitch.social @typhlosion I prefer NT 3.5's look
Enjoy this wonderful (and wonderfully '80s) track, "Strong as I Am" by The Prime Movers, featured in one of the best films of the '80s, Michael Mann's _Manhunter_.
What I really would have liked were some alternatives for acidimetric standards. "Tris" base, tris(hydroxymethyl)aminomethane, is a good one but not easily made at home! Another I found out about was 4-aminopyridine, also inaccessible. I tried and failed to synthesize potassium bicarbonate by passing CO2 gas into a K2CO3 solution.
Acidimetric titrations are a bit more work to prepare for. HCl solutions made from hardware-store muriatic acid are easily prepared, but standardization is more difficult. I had best luck with:
Sodium tetraborate decahydrate (prepared by recrystallization of commercial borax at 55 °C, and stored in a container with a high humidity to suppress efflorescence)
Sodium carbonate (prepared by baking out sodium sesquicarbonate prep'd by crystallizing a hot NaHCO3 solution)
For alkalimetric titrations I used solutions of NaOH made from hardware-store lye, and standardized with the following:
Oxalic acid dihydrate (recrystallized commercial Daly's oxalic acid)
Sulphamic acid (recrystallized TileLab sulfamic acid)
Potassium tetroxalate dihydrate (prepared from oxalic acid and potassium carbonate and recrystallized) (this compound is less satisfactory as a standard)
@Wulf @kibi@dev.glitch.social Honestly that _does_ sound like an improvement. (I had someone tell me why long bios with meta-information was supposedly not a practical idea for Mastodon but I never quite understood the reasoning.)
I've done volumetric analysis at home. For fun. Burets are fairly easy to get online ($20 will get you a serviceable 50 mL model) but availability of pure reagents for use as "primary standards" (for standardization of volumetric reagent solutions) is nonexistent to the private citizen. I taught myself to prepare and recrystallize a number of inorganic compounds in order to do my work.
@Wulf That is a rather provocative statement. What bears it out?
