You don't have to mess with batteries. I use 40% Sulfuric Acid sold fresh
as "battery electrolyte" for about $5 per quart at a automotive parts store.

Subject: Basic chemistry question

I have a process where I have discovered that I can use sulfuric acid to
improve image quality. As most know there is a large charge to ship
"dangerous" stuff across the country. AND, I see numerous car batteries (
lead acid ) waiting in stacks at tire and other stores. Knowing that they
started out with sulfuric acid in them I was thinking / wondering what it
would take to re-cycle this material into a few images?

SO here are the questions:

1. How do I refine the acid from the batteries to get relatively pure
sulfuric acid?

2. How do I measure the purity / strength of the acid? Is pH the best
guide?

3. I can not remember if a charged battery or a discharged battery has the
most acid?

I live in a 200 sq. ft house and plan to do this in my bathroom.....NO NO It
will be done outside! Most likely in the garden where acidifying the soil
would be an advantage.
