Although acetanilide and phenacetin aren't appreciably acidic, acetaminophen(like aspirin) is a stronger acid than water.what problem would you encounter if the unknown component were acetaminophen rather than acetanilide or phenacetin, and you extracted the aspirin with 5% NaOH? explain, giving equations for any relevant reactions.
A small amount of solid AgBr was added to a 0.0100 M solution of NaBr, causing it to become saturated with AgBr. A silver electrode was placed in the solution along with a reference electrode, whose electrode potential was 0.246 V
