does a little does of something effect a lot??????

Question

If there was a swimming pool with about 30 gallons of water in it, and a person put their hands in it after dipping it in tide bleach and dipped it in there 4 or 5 times would it effect it a lot???

Answer 1

It might kill some bacteria

Answer 2

Well, define "a lot".
30 gallons is a pretty small swimming pool, that would be more like a bathtub.
I'd expect dipping your hands in nearly pure water would rinse most of the Tide bleach off of them.
I'm guessing that maybe an ounce of Tide bleach would be on your hands to start with, so most of that ounce would end up in the "pool".
30 gallons would be 30 * 128 = 3,840 fluid ounces.
So, there would be 1 part Tide bleach in 3,840 ounces of water.
That might not sound like much, but the effects of many chemicals are measured in parts per million. That would be about 384 parts per million, which would definitely make a difference as far as cleaning something in that 30 gallons, or bleaching something in that 30 gallons, or even killing microorganisms in that 30 gallons.
