Then again at the minute amount of 5N you use it might
be fine as long as you get the correct dilution.


I suppose its possible its not pure, but for two bucks for almost
two liters I couldn't refuse. I'll be trying it on test strips first.

The concentration is more to my liking than reagent grade
meerly do to the handling issues.

I'll be calling B&H for control strips tommorrow (which is a special order)
any where you know of the might stock actually them?

It's been years since I knew of someone who kept a stock.

A good E6 lab might (or would sell some) but usually they
use the rolls. You want the 5 inch strips.

Make sure they ship them on ice...

Any idea what the percent is of regular car battery acid?


The acid sold as a replacement electrolyte in car batteries is
around 35% Sulfuric by weight. The electrolyte in the battery varies
in concentration depending on the condition of charge. At full charge
it is around 40% at discharge its around 10%.
Most photographic formulas call for concentrated Sulfuric Acid
which is between 93% and 98% by weight.

You're using new acid right. You're not dumping your car's battery into a
grad right? The car battery acid would have a lot of lead compounds in
solution I think.



Its fresh, and only cost two bucks.


Cool, and that's from a battery retailer? I'll need some for bleach
when I'm ready to do reversals...
