Electrical conductivity with salt water

Experiment for vision only, it is used to understand how the salt dissolved in the water facilitates an optimal condition for the passage of current between the two electrodes. The working voltage is 220 volts AC.
Required: 500W 220V bulb. Two conductive iron or other metal nails, glass tray. Salt water and two electric wires.

The arcing against the water is very cool!!! I should have expected it, but still surprised me when it happened.

Salt is not producing the energy but conducting it as a metal with charges Na+ Cl- .on the periodic table Na is located on the left side and Cl on the right due to the need of valence electrons, in this case Cl requires one and why has a charge of minus (-1) to complete the octon rule, so in other words Cl consists of 7 valence electrons. Salt is also considered a crystal salt due to the properties just mentioned.

The bubbles coming off the electrodes in the water are O2 and H, you can capture this in a test tube then make it burn with a match and get a nice pop. Don't use a huge bottle though as it is very explosive. To capture the gas, but a test tube of water over each electrode, as the tube fills with gas it will empty the water. The tube that fills first is the hydrogen and the slower one is the oxygen.

Thank you. Salt of the earth and light of the world does make sense now.

Pure water (distilled) is a very poor conductor of electricity. That good ole salt always does the trick. TDS(Total Dissolved Solids) meter work by testing the conductivity of the water. no conductivity, no dissolved minerals/solids. Good conductivity, lots of dissolved solids. Now you know why sweaty hands conduct so well. Nice video.

Fascinating... I have seen this technique used for arc welding... almost like the salt water solution servers as a sort of capacitor to store energy and release it at the contact transience...

Guys the chemistry behind that is quite simple.

NaCl is dissolved in H2O...red wire is the anode and black
is the cathode which leads us to following half reactions:

Anode: 2 Cl- __to__ Cl2 + 2e-
Cathode: 2 H2O + 2e- __to__ H2 + 2OH-

Overall reaction: 2Na+ + 2Cl- + 2H2O __to__ Cl2 + H2 + 2Na+ + 2OH- (dissolved Sodium hydroxide_NaOH)

So the evolving gases are H2 and Cl2, BUT: since the
products of the reaction are not separated by a membrane, the Cl2 gas reacts
with 2OH- to form OCl- (Hypochlorite) + Cl- + H2O
Thus it is somehow dissolved Sodium Hypochlorite (NaClO)

Thank me later...
Aww.. I have forgotten to mention that O2 is NOT evolved
since the oxidation potential of Cl- comes first, so Cl2 is formed. To form O2,
all Cl- have to be removed by gaseous Cl2. But things get complicated as Cl2 is
not only removed but also reacts to Chlorites which are soluble in water. So
ClO- is involved, possibly also chlorates and perchlorates which makes it hard
to remove chlorine from the water.

I saw this on the Internet before...besides, the technique of this experiment and the brightness of the bulb is super cool! Metal and salt water is a conductor of electricity..

[tostoamico]

Can you post a video of the same experimentation without connecting cables with the voltage counter device?pls.

[anilrawat]

caption should have been that salt water is a good conductor of electricity.

[RODALCO]

Great experiment, interesting how much heat is generated by an arc. It melts the iron very quickly.

@ syed adnan
Hi, for a scenographic effect appreciable it takes a voltage of 230 volts and a minimum load of 300-500 watts..

[leosypher]

thank you, I was wondering if I could use salt as an alternative to hydrogen sulfate, well I guess I can, so thanks for making this video

[ambigasundereasan]

He explained without even opening his mouth for me good channel

[guitarXshredder]

Regular water = Insulator, Salt water= Conductor. He made a path. Is pretty much what this video is.

[gortsneeley]

To all readers: this is a nice experiment but it has absolutely NOTHING to do with 'free energy' and should be on a different channel, such as 'Simple Science Experiments Teens Can Do At Home". The poster uses a source of DC current (also known as MAINS AC) that is, a transformer, to bridge a connection between a copper wire and a light bulb. THAT IS ALL. The salt water is a great conductor and, unlike the copper wire, it can be destroyed and consumed to conduct the energy coming from the MAINS AC (it is converted to DC by an Inverter; the poster wrongly calls this a Transformer. He should call it an Inverter so there is no confusion), through the salt water, into the light bulb filament; the RESISTANCE in the light bulb's filament is MUCH HIGHER than that of the salt water or the copper wire, so it GLOWS. That's about it.

[thomasdacey]

That was really interesting!! Thanks for sharing this.

[keithnoneya]

This is not DC Voltage it's AC voltage, as DC does not oscillate as shown by the Hz meter . Other than that pretty cool experiment. Oh the bubbles are HHO gas and is highly explosive in large quantities, so no letting this gas get to thick, sparks around this will cause it to ignite, so do it in a well ventilated area. Best Wishes and Blessings Keith.

[Sterling_Archer]

What is the Hz thing you are plugging the wires into? Is that needed or is it just for measure output?

This guy seems to be a welder at heart. I wonder if this setup can be used as a cheap (although dangerous) arc welder. Amperage could be adjusted with different light bulbs.
