I never thought about this question until my lab manual asked it. Because I was having an experiment and use the H2SO4 to disslove the FeSO4 and use titration to calculate the moles of the unknown FeSO4. I think it has something to do with the SO4(2-) thing because they both have it. Tell me if it is ringt or wrong. Futhermore, the lab manual asked for two explaination. Please DO tell me where the data you refrence or cited. Monash university is really stric about it. Thank you!!!

By the way, am I considered plagirism or cheating if I ask homework like this?

I was just wondering... I have a graphing calculator... but are there functions on a scientific that chemists prefer? I'm just starting college.. and I want to make sure I have the right materials. Also, do chemistry professors dislike people using graphing calculators on tests?

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!
