SPLITTING WATER

 Question
How much chlorine can I produce by splitting salt water with
electricity? WiII I see a difference if I change the amount of salt in the water
and the amount of voltage in the current?
Hypothesis
My hypothesis is that I expect to see the most chlorine produced
when I use the greatest amount of salt and electricity. I expect to see more
chlorine produced faster when I use more electricity and more chlorine
produced generally with more salt.
Abstract
The purpose of my experiment was to measure the amount of chlorine
produced when water molecules are split. The procedure used was to
connect stripped bell wire from batteries to the graphite of pencils and
measure the amount of chlorine produced with pool test strips over one
minute, five minute, and ten minute intervals. I used three different levels of
salt and two different levels ofelectricity. I found that increasing the salt
level raised the chlorine level and increasing the electricity also raised the
chlorine level, and the most chlorine was produced with the greatest amount
of salt and electricity.
