Substitute glacial acetid acid with 98% acetic acid?

How will it affect a particular reaction involving 30% H202 and glacial acetic acid, if I replace glacial acetic acid with acetic acid ~98% or maybe even 75%? I mean, the H202 contains water anyway, I just have to change the ratio between them is my thought...

any suggestions?

Ps. It's probably a stupid question, so just delete it if it's too stupid Ds.

Well, it really is a stupid question.
If you are going to put 30% H2O2 together with acetic acid what difference can a little water make when you have 70% of water in the first reagent anyway?

I just wanted to make sure that it really was a stupid question so I can forget about the glacial acetic acid and stick to the less expensive non-glacial acid

....Glacial Acetic Acid is ~98% Acetic Acid....

, .....Acetic Acid without water is Acetic Anhydride Actually, the glacial is 100% waterfree acetic acid ............

Well, not to burst your bubbles or anything
but neither of these statements are correct according to ACS and this label on the bottle (GAA RA grade) has a water content of .02% (Karl Fischer).

Anhydrous reagents usually aren't truly and require special treatment to remove last traces of water for some purposes. Like this bottle of Absolute Ethanol which ain't.
