Steve's Science Fair Research Report:
Which types of liquid does not conducted to electricity out of salty water, sugar water, pure water, oil, and vinegar?
Science Report
My science project is about the liquid that doesn’t conduct electricity. The reason that I wanted to test in this experiment is that people died because of conducting liquid in the movies. For example, in the movie shown tsunami, the electricity battery fell into the tsunami and people who got attack by the tsunami were killed because of the electricity shock in the water. If I know which types of liquid are not conducted to the electricity in the water, I could be much safer and learn about some new knowledge.

First of all, let’s see what kind of material or substance can conduct electricity. Here are some stuff that can conduct electricity. These are silver, copper, gold, aluminum, iron, steel, bronze, brass, concrete and more. Now let’s see some stuff that can’t conduct electricity. These are glass, rubber, oil, asphalt, cotton, paper, wood, plastic, air, diamond and more.
Most people believe that most liquid conducts to electricity. But the fact is that some liquid doesn't conduct to electricity. It depends on what kind of liquid and what types of substances are in the liquid. Meanwhile, the substances that make the liquid not conducting is called non electrolyte (diagram 1), but how about the water that is pure and have no non electrolyte in it? Because there is no substance that helps to conduct the electricity, the pure water doesn't conduct to electricity. So mainly, the pure water doesn't conduct to electricity.
On the other hand, when the substance melts into liquid and that liquid is conducted, the substance that is conducted is called electrolyte. There are many types of electrolyte, (diagram 2) such as acid, salt, and calcium, so salty water will conduct to electricity. But sugar, alcohol or other types of substances will not conduct to electricity, because they are not electrolyte.
How about Vinegar? Since Vinegar is one type of alcohol, electricity will not conduct. Also, oil will not conduct to electricity because, if they meet, they might cause fire because of the crash between the substance in oil and electricity. So even though people think that most liquid conduct to electricity, there are some types of liquid that don’t conduct to electricity.
