Title: Chemistry question
Post by: Tausami on February 27, 2011, 11:57:22 AM
If you mix salt and baking soda, and put it in water, and preform electrolysis, what would you get?

Carling.

Hydrochloric acid, sodium hydroxide and carbon dioxide. I can't remember the valencies though, so I'm probably wrong.

Thanks

I think the main thing you would get would be hydrogen and oxygen gas.

I know that if you use salt, you end up with chlorine gas, because Chlorine is oxidized preferentially to water, and sodium would reduce preferentially to Hydrogen.  Although this doesn't work out perfectly and you end up with some interesting chemistry.  I know my explanation is shit, but it's been 12 years since I've done redox reactions.

You would end up with the above mentioned mixture....and no hair.

You'd have toilet duck.

I know that chlorine oxidizes with preferentially to water, which means that it is happier being in its ionized form then water is being water meaning that water breaks down first right?
I swear that I used to see people at the science museum preform electrolysis with salt water. granted I could be wrong but the 5 minutes I spent googling it seemed to implies people use saltwater to for like home electrolysis which I doubt would happen if it produced chlorine in greater concentrations then oxygen and hydrogen. again I could be wrong but that is just based on what I remember from chem.

I remember using salt water and burning my nose when I inhaled what I thought would have been oxygen but turned out to be chlorine.  I'm almost certain that the voltage used makes a difference as to what gets produced.  Again, it's been 12 years since I've dealt with redox reactions.
