acidic hydrogen means which attach with more electrondonating  group. always remember that sp hybridized carban  attach hydrogen is more acidic . in tauto merism atlist one alpha H atom is required for come out to hydrogen and  become enol content.alpha H means attach  alpha carben atom . if it is acidic or not always remove alpha H. mostly alpha H is acidic in tautomerism,
