When a snake bites a snake does that snake die?

Nope.

depends on the snakes involved- a king cobra bites another snake,that snake should die, when a king snake bites another snake, and eats it- one snake is dead and gone. I know king snakes are not venomous- but they do eat other snakes. I believe king cobras feed on snakes as well. I don't think that if a rattlesnake bites another rattlesnake, that one of them would die. only snakes of different species- with different kinds of venom.

depends on what snake and how hard it bit it!
or If it has any poison!

well the snake that bite the snake wont die but if the snake that got biten, got bitten with poison ti might die depending on how thick the bitten snakes skin was and how much poison was injected.

Depends on how strong the snake is
