9 speed is narrower. The gears are closer together on a 9 speed cassette, so they fit into the available space.
9 speed chain might work on an 8 speed gear set, but I haven't tried. I have tried an 8 speed chain with a 9 speed gear set, and it doesn't engage with the gear teeth properly, so you end up with the gears skipping horribly with the slightest effort.
Just get the right chain, anything else isn't worth the hassle.

Btw, 10 speed is also different.

9 speed chains are narrower both in outside width of the chain pins, but also the inside width of the rollers between the chain link plates to match up to the reduced width of the teeth of 9speed chainrings and cogs.

Most singlespeed rings/cogs use teeth that are 1/8" thick, multispeed drivetrains from 5 to 8 speeds use teeth that are 3/32" thick, and nine and ten speed drivetrains use teeth that are 11/128" thick.
