Drain Cleaner
Hi,
I went to the store to find drain cleaner that contains H2SO4, unfortunatly I couldn't find any brand that contains it. Does anyone have any
recommendations on what brand I should look for?

What country do you live in? It might help narrow the search ;-)

H2SO4
The best brand of H2SO4 that I have found is "Rooto". but I remember back when there was a brand like "DJ plumer" or something.
Ofcource theres always the nasty black H2SO4 with brands like "Liquid fire".

Go to Home Depot, look in the plumbing section, and look for the drain cleaners that are wrapped in the heavy plastic bags. I don't remember the
brand name-- it may well be Liquid Fire -- but this is probably the purest H2SO4 sold OTC. The other ones tend to have the black dyes and such, but
Home Depot's do not; it's the slightly yellowish, transparent, oily liquid that Sulfuric Acid should be.

The best sulfuric I've personally encountered is "Instant Power" brand. 93% concentrated and pretty clear as well.
Great ideas often receive violent opposition from mediocre minds.

If you want sulphuric acid, why not try and visit an agricultural store or hydroponics? they have 98% sulphuric acid for adjusting pH of hydroponic
gardens, sold by relatively large (10-15Liters) and very cheap - often the same as 1L bottles of drain cleaner

Europe
And for the poor EU members I disclose this source:
"Stura Facile", yellow bottle, made in Italy, 98% H2SO4. Should be available in all EU countries - have a look.

Obtaining Sulfuric Acid
Save your car batteries and filter the lead catalyst out(or use a glass baster to baste out the H2SO4 from the settled lead particles)
Put acid in the pan on a stove and open all your windows.(Do this in the summer after 6 pm.Besides who has windows open before 6 pm in the summer)Turn
on one fan blowing toward an open window and two other fans blowing out the window.Turn on stove on high heat until it starts boiling(do not breath in
fumes).Turn heat to low and go out for coffee for an hour or two.
Turn off stove and let acid cool.Leave windows and fans going until 11pm.Keep windows open all night and close them at 6 am.
Store acid in a glass jar labelled with nessecary warnings and precautions

Purity
A few weeks back I determined the strength of some Rooto brand drain opener with H2SO4 (US). According to my titration, using NaHCO3, it was just
slightly stronger than the assumed 93%. I've been letting the water evaporate from the Na2SO4. And I can see that there are some impurities in
it. Little orange-brown blobs that look kind of like dirty oil. Compared to the amount of Na2SO4 produced, I'd say the impurities are small -
but they are very noticable. I'm guessing that these impurities were in the drain cleaner, as I doubt they would be in food-grade baking soda.

HCl only goes to ~38-40%. The only way you're getting above probably 30 or 40% of a chemical is dry, sulfuric excluded of course. In this case
it'll be NaOH without a doubt. At least partially NaOH.
Generally drain cleaners wont be a good source for most chemicals. Sulfuric, NaOH, and maybe HCl are the only you'll be getting at a decent
purity. Often times they contain buffers, thickeners, surficants, and some other random preservatives.

I have not encountered any sulfuric acid at Home Depot, but Lowes sells two brands, Roebic and plumbest virgin sulfuric acid. ACE hardware has liquid
fire. All are black if you look at them through a full 1 L beaker, some look yellow if only a few drops. I really don't care, because when you
distill nitric acid the impurities don't distill over. Samosa, sulfuric acid is not yellow, it is perfectly clear if pure, that's why you
might consider buying diluted battery refills about $15 for 5 gallons, and boiling down. 1-1.5 gallons of 98% sulfuric acid for $15 isn't bad.
I have heard that rooto and instant power are the two best but have not been able to find them, are they clear?

In small amounts they are almost clear. Rooto at least. Larger amounts it takes on a yellowish color. Even a brown at times. My color varies
depending on fullness of the bottle. Generally gets darker as the acid level goes down. This tells me there is particulate impurity. There is a dye
of some sort. Turns dark upon boiling to 98% Dark brown to black almost.

know, the wrong person gets hold of it.

Theres no way the government can keep track of OTC goods especialy if payed for with cash. I couldn't imagin it being hard to find the correct
drain cleaner at any hardware store. I use the Rooto brand I believe and it is about 95% purity and only slightly dyed. Works great. Don't waste
time trying to heat it to 98%, it's pointless.
