how to make a salt water circuit

Everyone tells you that when you enjoy a long soak of hot water, don\'t put the appliance in the bathroom near the tub.
It\'s good to listen to music in the bathtub, but put the radio on the edge of the bathtub. . . . . . . . .
Definitely not a good idea!
Most of the water contains minerals and salt.
Those of us who like to drink soft water with a pleasant scent can also add washing soda, which can even provide extra salt.
But why is this a problem?
Read dear readers and discover the dangers of electrical appliances near the bathtub.
Consider common salt or cl-consisting of sodium and cl-ions -.
All atoms want their orbital shells filled with a certain amount of electrons.
If its number of electrons is far less than the required number of electrons, atoms tend to give up electrons, and atoms tend to get electrons if its number of electrons is almost correct. Sodium (Na)
There are eleven Electronic
It has too many shell layers, so it will give up an electron to an atom that needs a shell layer.
Chlorine has 17 electrons, and only one more electron is needed to fill its outer orbital shell.
When chlorine is in contact with sodium, sodium gives one of the electrons to chlorine.
Although they have now filled the outer electronic shell, they have all undergone chemical changes.
The addition of electrons changes the charge of chlorine from neutral to negative.
Chlorine becomes an ion with negative electricity.
After the electron is lost, the sodium changes from neutral to positive electricity.
Sodium becomes an ion with positive electricity.
Chlorine and sodium are strongly attracted as positive ions and anion and become compound sodium chloride or salt.
As a dry compound, sitting on your table, the strong attraction between the two ions in salt is very strong and it is almost impossible to be broken.
However, putting these salt into the water, these ionic bonds are easily broken due to their electrical attraction to the water.
In other words, salt is dissolved in water due to the weakening of ion bonds in water. Na+ and Cl-
Ions float freely in solution.
Because there is positive and negative electricity, salt water (
Most water does contain some salt ions except pure water)
It is an excellent electrical conductor.
If you are in the bathtub, your living appliance falls in the bathtub with you, and the current is transmitted directly to you through water, often causing serious injury or death due to electric shock.
Therefore, never treat electricity in a casual way.
Always be very careful, and even this experiment should be carried out under the supervision of parents while young children are in progress.
Please never put the appliances near the bathtub!
Material big mouth Cup tape for making salt water circuit-
Water or city tap water (
Too many minerals in the well water will distort your discovery)
Table or sea salt 9-
Small voltage bulb (volt)3. 7-
Volt will work very well.
The bulb connects two popsicles or two pieces of cardboard of similar size insulated copper cables or lines. The salt water circuit completely wraps two popsicles in a layer of aluminum foil.
These will be electrodes.
Cut 3 insulated copper wires 6 to 7 inch.
Use a scissors or wire stripping machine to peel off about inches of insulation from each end.
Connect the stripping part of the end of a wire to the positive pole of the battery and fix it with tape.
Peel the other end of the same wire to the side of the bulb socket.
Using the second wire, connect one of the stripped ends to the other side of the bulb socket.
Peel off the other end of the same wire, tape on aluminum foil near the top of one of the \"electrodes.
Using the last wire, connect a stripped end to the negative end of the battery and secure it with tape.
Follow the way outlined in step 7 to peel the other end of the same wire to the second electrode.
Check all connections in the circuit and make sure they are safe.
To test your circuit, make a complete circuit by touching two electrodes.
The light bulb should light up.
If it doesn\'t check your connection again and make any necessary adjustments then try again.
Use the brine loop in the water to pour distilled water into the cup so that the cup is full.
Do not let them touch, put the two electrodes into the water.
What happened to the bulb?
Remove the electrode from the cup and put two teaspoons of salt into the water and stir until it is dissolved. Repeat step 2.
What happens to the bulb in this case?
The science behind the circuit when salt water is dissolved in water, sodium chloride (
Chemical name of salt)
The positive and negative chloride ions are removed.
Since there is a positive and negative charge in the brine solution, the electricity can be transmitted from one electrode to another electrode in the brine loop.
These charged ions complete the circuit that causes the bulb to light up.
Try changing the amount of salt dissolved in the water to see if the brightness of the bulb changes.
