OK so, stupidly busy at work right now so by the time I get back my brain is usually roughly the consistency of cottage cheese. As a result of which I have mostly spent the last week reading crap fanfic because that genuinely IS the only thing I can be bothered to do.
As a side result of which, for the love of fuck, people writing gay sex where they make a total point of using a condom for anal because of the potential risk of disease, but completely don't bother for oral... you ARE aware infections can be transmitted both ways, right? A naked blowjob followed by a condom for anal is self-defeating. It's not like it's neccessary for contraception, which would be its only other possible purpose at this point (unless that's your trope of choice, of course.) All you're succeeding in doing is potentially reducing the clean-up later. But after three pages of lovingly-described come-play and snowballing I'm guessing the mess ain't your primary concern.

In other news, are there any chemists on my flist? I need to ask a question and Flopsy was being vague at me, which is not a lot of help. It's one of those moments where my Friday afternoon google-fu fails me because I'm too wiped to even know what I'm talking about any more and my actual knowlege of the mechanics behind stuff is a little bit non-existant. Which is a bit of a disadvantage sometimes.
It's about a transition metal titration, using (neutral) potassium dichromate VI solution to calculate the concentration of an Iron II sulphate solution. The experiment sheet from the board calls for the addition of 1M sulfuric acid mixed with a quantity of concentrated phosphoric acid. Now, when we do a similar test-tube reaction experiment, we use just sulphuric to acidify the solution to get a clearer reaction from the dichromate, and a brief run through of the titration experiment seemed to yeild results without the phosphoric being present.
But I honestly have NO CLUE if the phosphoric would actually be doing anything to affect the results significantly other than more strongly acidfying the mixture.
(It basically comes down to the fact that we really don't have a lot of phosphoric acid and adding it where it isn't needed to make corrosive solutions when merely irritant ones would suffice means it's a combination of both budgetary and Health&Safety considerations.)
I may have to ask Not!Steve on Monday because at this end of the week my brain is pudding (PUDDING!!) and I know I should be able to work it out, but I'm just sitting here dribbling and getting pointlessly and off-topically irate at people on Tumblr who don't understand the concept of being facetious.
