A pal's business recently bought 55gal of surplus 98% sulfuric acid. Unknown buffers or impurities give it a dark brown color (clear not cloudy) .

The problem: The dark coloring makes the product unusable for their application. It must be as colorless as possible. To avoid wasting expensive product and disposal fees, they want to try to remove some or all of the color. Distillation won't work as 55gal is too much for them to process safely & quickly. They're willing to try any reasonable method that might possibly help.

1: Basically, they need to know what readily-available filter media can withstand 98% H2SO4 (and might clarify the product even slightly).

2: If filtering isn't possible, what chemical reactions might clarify the product? Again, even a modest improvement might be enough.

This is a small shop that sunk lots of cash into this product. I'd hate to see them lose money if there's a chance the product can be salvaged.

10 pts. await for the best answer. Thanks!

For 0 < x < 1, the expression x^x^x^x^x.... oscillates between two values B < A, where A = x^x^x^x^... with an even number of terms and B = x^x^x^x^x... with an odd number of terms. For example, 0^0 = 1, while 0^0^0 = 0^(1) = 0. Show that for small x approaching 0, the infinite expression x^x^x^x.... approaches 0.

I have heard this my whole life; that shrimp are the underwater cousins of cockroaches. Is this true? Also I have heard that lobster and crab are just really large insects. I have an aversion to seafood (excluding fish) because of this rumor, or fact or whatever it is.
Is this fact or fiction? Any scientific proof or a link providing info on this subject would be greatly appreciated.
