H2O2 (hydrogen peroxide) is "acid" or "acidic".

As the dictionary shows, "acid" can be used as a noun or adjective and "acidic" can be use as an adjective only. Which one is correct in the sentence above? If both, which one is better in this situation? Thank you.

    I think in chemistry 'acidic' is the usual adjective. 'Acid' is more for sharp-flavoured sweets, or figuratively for remarks.
