A salt water solution and a baking soda water solution both have a current applied to them. The salt water turned yellow during the short period of time the current was applied. The baking soda water turned a light blue. Any comments on the color change?

Salt Solution …
Salt Solution turned yellow becuase of the presents of Iron(III) ions which on contact with the water formed Iron Hydroxide Fe(OH)3.
The Sodium Bicarbonate solution turned blue becuase of the Copper(II) Ions that formed Cooper Hydroxide in the water.
A Very good demonstration thank you.
Bicarbonate Ions.
Bicarbonate Ions.

In the salt water: …
In the salt water: ClNa splits to Cl on the positive pole, and Na on the negative pole. Then the Na reacts with water and produces NaHO +H2. The yellow thing is Clorine gas.
copper related?

well if you to it …
well if you to it to 60 liters of solution and are planning to make some industrial amount of chlorate or carbonate, you shouldn’t have a problem with that kind of power. Except your anode and cathode will… just die.
AC current doesn’t …
AC current doesn’t work as well anyways I think. I’ve never been foolish enough to try it
I guess the 120V supply from your house will result in super fast, yet very possibly lethal electrolysis
colour change due …
colour change due to the salt burning, this happens at a slower rate with “dc”12volts, but happens nun the less, soda slight coulour change too…. remember salt produces a dangerous gas, poisinous to humans so take care….. thom scotland. oooo to slow down salt burning use some cream of tarter powder…
heads up if your …
heads up if your getting arc-ing like that then your voltage is way too high so ether move your electrodes apart or lower the voltage.
Just using a/c out …
Just using a/c out of the wall will just heat the water – like a vaporizer. That is all they are, two electrodes submerged in water. Use d/c (preferably out of a transformer for mains isolation) and you’ll end up with hydrogen on one electrode and oxygen on the other. As far as the color change, maybe from the electrodes? What were they??
that was beautiful …
that was beautiful the lightening effect
Lol, blew the …
Lol, blew the breaker a few times actually.. Decided after the second time I ought to use a safer method.
omg dude strait off …
omg dude strait off the wall?!?! , haven’t you like blown a fuse yet? i use an old computer power supply it’s safer, much much safer than what you are using, but of course much slower, buy hey safety first.
Lol not a safe one. …
Lol not a safe one.. Just regular 120volt plug socket straight out of the wall..Lol i know its dumb and not safe.. I’m just careless..
hey what kind of …
hey what kind of power supply are you using?
hahaha, hands dry. …
hahaha, hands dry. You do realize that you don’t need to have wet hands to get electrocuted right? I remember chatting with a guy that was using an arc underwater to produce hydrogen. He stopped because one day after his experiment got the HHO combo perfect and, well, BANG! He filled his lab with shattered glass. Most of the time its ok, but you must not forget how volatile these kinda experiments can be. Hope you at least wear goggles.
Lol this makes me …
Lol this makes me wish I’ve recorded half the things I’ve done with explosives. Then you would would say they are the most dangerous things you’ve seen on youtube. When I was doing this I did make sure my hands were dry and the ventilation was good in the area. anyway, glad to entertain. take care
that has gotta be …
that has gotta be the most dangerous deliberate thing I’ve seen on youtube for a while. Yikes!
The arcing is igniting the hydrogen and if you were to get enough of the hydrogen and oxygen together you would have a nice little pop, which might have been enough to make you jump and touch the wires together. If you don’t electrocute yourself or burn yourself, then have the chance of poising yourself with the ammonia you are also creating.
Jice job though, cause I wouldn’t try it.
Thanks
on the salt forms …
on the salt forms yellowish solution of lye or sodium hydroxide NaOH.. the other one blue color probably is mixture of copper hydroxide[blue] and some copper carbonate[greenish powder]
I have not tried …
I have not tried much really. Just got bored and messed around with baking soda and salt.
Have you tried …
Have you tried sodium hydroxide? (lye)
As a journeyman …
As a journeyman industrial electrician / electrical engineering technologist you shouldn’t be doing that with 120vac! If you remember back to chemistry class you use a 12 volt dc battery. With normal water put a test tube filled with water or whatever above each electrode, one will have get hydrogen and the other oxygen. Light a match to find out!
u mean carbon …
u mean carbon dioxide…
the salt solution …
the salt solution turned brown because of the iodine
I’m pretty sure …
I’m pretty sure Copper salt solutions are blue, so that may be the source of the bluish color (i.e. the copper wire).
