Question about creating chlorine from salt and water.?
My goal here is to create a solution to purify water.
I am using 60g of salt to 1 liter solution. I am making about 125ml of solution at a time. I am using tap water that has been filtered through an activated charcol filter (brita), it does not have any chlorine in it.
I have tried AC current (120V) and three AA cells (600Mah 1.5V) wired into a functional battery. None of these things have worked though I am doing something because the water is changing color from clear to a lime green.
I appear to have a high ph level (around 8.4) according to the test strips.
The container is a coffee mug.
I have no clue what I am doing but if anyone could assist me that would be great. I seem to have followed the directions provided to me but I can't get it to work.
Answer:
Your chlorine is evaporating, that is why you are not detecting it.
Here is what I think
If you perform this experiment with just water you will get bubbles of gas coming off both wires. One is oxygen(anode), the other is hydrogen(cathode). If you add salt to the mix, you should get a whiff of chlorine gas. You are basically creating aqueous sodium hydroxide and chlorine gas which will come off of the anode. Any sodium you electrolyze will react with the water and start to form NaOH, which probably explains why the solution is going basic. The products you get from the reaction are very minute, so here is what I suggest.
DO not test the solution itself because the only thing in soln is NaOH and the color might be due to the slight formation of the precipitate copper hydroxide. Instead Try to hang the chlorine test strip over the anode and see if it changes color
