CONDUCTING SOLUTION

Conductivity Tester

 CONDUCTING SOLUTION

Holy water, Is not conduct electricity very well. However, the solution of some substance are dissolved in water, is conduct electricity. It is a simple tool that shows how a solution that can conduct electricity. This device uses a flashlight bulbs indicate how the solution conducts electricity. Better solution conducts electricity, light bulb conductivity tester you will need to build glow.To:



 Conductivity tester to build you will need:

● 12 volts AC Adapter
The 110 volt 12 volt power from a wall socket converts. The 12 volts AC, not DC, because DC will not work for him. You are using an old tool around a house by the appropriate adapter, or an electrical (eg radio shack, catalog number 273-1631), one can shop.
● A 1/4-inch or 1/8-inch monaural plug on one end of the audio cable
Plug for conductivity tests will be conducted. Around your home can be an unused cable. On the other end does not matter because it will be removed. You supply electronics store (for example, radio shack, catalog number 42-2381) by a suitable plug and cable assembly can get.
● a 12 volt flashlight bulb and socket
How visible signal bulbs to provide holding power. You can get it from an electronics store (for example, radio shack, catalog number 272-1143 socket for the bulb and 272-357).
● 4 1 about 4 inches from wooden blocks
Electrical connections will be blocked, and the lamp on it.
● Two 1-inch wood screws
The wooden block stop lamp socket.
● a 3/4-inch round screw head and washer
It will be used to make electrical connections.
● Wire cutter and wire stripper
It is used to produce electricity connection.
● a screw driver

Disconnect the AC adapter plug end of the cord. About four inches of cord that separate the two conductors. 1 inch of insulation from each of the conductors remove.

Plug the audio cable cord about 2 feet cut off. About four inches of insulation from cable end kit to remove. The bare stranded wire insulation that covers the exposed wire is wrapped around. Unwrap the insulation stranded wire and twist the strands together to form a bundle. Internal insulation from the wire about 1 inch belt.

Electrical connections

Wooden block lamp (socket) on the basis of using the wood screws. Round head screw with washer and screw in lamps on the block, but still not tough patch.

AC Adapter around the top screw washer (does not matter which) and a string wrapped. Audio plug patch around the end of the wire wrapped bundle. Fasten a firm with two patch cables.

AC adapter lamp base with the wire attached to one of the terminals. The other terminal of the lamp plug the audio cable connected.

Lamp base lamp 12 volt flashlight hell.

To create a more secure connection, using a large master block of wood on each of two wires can be held.

Conductivity tester is now complete and ready to use. Test the AC adapter plug it into AC outlet works. Lamp will not light. A piece of metal, like a coin touch audio plug sideways. When plugged by two metal conductors that are shorted, lamp shining brightly. Bright glow indicates that the current is flowing easily through a piece of metal

Testing a solution

Put some water in a cup. Audio plug end into the water. If you use distilled water, light, no flash. If you are using tap water, candle glow, dimly if you can. If it glows, it shows that tap water conducts electricity only poorly. Add some table salt into the water and stir mixture. Lamp glossy shine when the plug is put into the solution, the salt solution conducts electricity very well, almost as well as the metal.

Also tried a few things, salt, sugar, baking soda, shampoo, laundry detergent, rubbing, alcohol, and are antacid tablets. Anything that dissolves in water can be tested. Are you content test to avoid mixing water and rinse plug in a different material before testing to ensure that it is dry. Solution for more than 15 seconds with 10 plug-cast, because doing so would cause the plug corrode rapidly. A record of the electrical discharge process, as well as, to a poorly organized, and not just take.

Sometimes, a mixture of different substances to different substances. As an example, check the conductivity of vinegar. Check the laundry conductivity of ammonia. After that, add vinegar and mix a small test for ammonia. The combination of different things and you'll see a big difference!

An electric current is a flow of electric charge. When a metal conducts electricity, the metal charge is transferred by electrons. Subatomic particles with electrons have a negative electric charge. When a solution conducts electricity, charge transfer ions from the solution is. The atomic ions or atoms that have an electric charge is small groups. Some ions have a negative charge and have a positive charge.

Pure water contains very few ions, it is also not conduct electricity very well. When table salt is dissolved in water solution, is very well organized, the solution contains ions. Table salt ions, whose chemical name is sodium chloride come from. Sodium chloride sodium ions, chloride ions have a positive charge, which has a negative charge is based on. Because sodium chloride is made up of ions, an ionic substance is called.

All substances are made up of ions. How much are uncharged particles called molecules. China is such a substance. When sugar is dissolved in water, the solution does not conduct electricity, because there are ions in solution.

Some substances are made of molecules that form solutions that conduct electricity. Ammonia is such a substance. When ammonia dissolves in water, reaction with water and some ions that form. That is why laundry ammonia, which is the solution of ammonia in water, conducts electricity, but not very well.

Sometimes, when you have two different solutions, are substances form ions with each other and react. This is what happens when ammonia and vinegar are mixed. A few anion contains ammonia solution, and it only conducts electricity poorly. A vinegar solution is based on only a few ions and conducts electricity is just a little bit. But when it got resolved ammonia, acid in vinegar (acetic acid) with a view and a form of ions. That mixture of ammonia and vinegar holding power very well ...
