A random old lady walked up to me and asked if I was autistic. I told her I wasn't sure, and she said, "Would you like to be?"

it is literally bed time. sleepy bye snoozing time. we're talking lights out, tucked in, snug as a bug in a rug. you wouldn't believe the type of shit I'm on. melatonin. sweet dreams

hey reminder to continue boycotting eurovision and instead turn your eyes on gaza where the last media outlet al jazeera has just been shut down so that Israel can launch its attack on the most densely populated area in the world without scrutiny. Dont stop talking about Palestine

guys I've been assigned two tasks at once ,please pray for me

Sulfuric acid sucess!! I concentrated it by boiling to >80%, though it looks a bit murky now, probably from the boiling chips and the clay pot that I used as a diaphragm. Nargh, even with those impurities (and the remaining water) it was able to burn through tissue paper, so I'm still haopy with the result.

Shrinkflation is wilddd; I just went to the euro store to buy some Hydrochloric acid, because my local hardware store reduced the concentration from 30% to 22-24%, and they still charge the same 5.99€ per liter; while the euro store I went to sells the old concentration for the same price.

(tbh the fact that they even sell HCl there is crazy)

I'm doing some electrolysis of a sulfate to make sulfuric acid, and I think I have found a cool coincidence: according to my calculations (tho I could easily have made a mistake), one Ah of charge equals something very close to 1ml of 100% sulfuric acid produced as a theoretical yield? huh, funny

maths I did:

(( (3600/F) /2) x 98,07) / 1,8302 = 0,999743645....

3600 is the electric charge in one Ampere hour, divided by Faradays constant to get the moles of e-, which is divided by two, because to go from a sulfate to sulfuric acid two electrons are needed, then I multiplied with the molar mass of the acid, and finally divided again with its density. According to my calculator the result of that is very close to one; which if I have done everything correctly proves that little coincidence of nature (first noticed it on the conversion fields in my spreadsheet that I made to track my theoretical electrolysis progress).
