Kio asks "what" about a thing, where kiu asks "which" out of a known set. It takes the accusative whenever it is the object, and that -n is the commonest slip of all: kio estas tio? but kion vi faras? Its ti- partner is tio, so kion and tion move together, and the whole correlative table teaches them in one pass.
