Practical Organic Chemistry - Confirm positive test

[AGNuke]

I don't know where to ask this question, but anyways, since it was asked in an exam, so finding out the correct answer afterwards is a moral responsibility as a homework. So here I am.

My question is whether the compound 2-Hydroxy-5-nitrobenzaldehyde (Did I named correctly?) gives positive test with NaHCO₃? I mean, will it give effervescence of CO₂?

All I know is 2,4-Dinitrophenol will give effervescence with NaHCO₃ as H in OH becomes acidic. So the same phenomena will happen here on OH's H because of Nitro and aldehyde group?

Yes slight effervesence should occur because the hydroxyl proton is slightly acidic
