Q:

Why is salt water a good conductor?

A:

Quick Answer

When salt dissolves in water, negative and positive ions are pulled in opposite ways by an electrical field, which creates an electrical current. The ions that are created include sodium, which has a positive change, and chloride, which has a negative charge.

Full Answer

Electricity can be defined as the flow of charges. A variety of minerals can dissolve in water to make it a better conductor of electricity. Pure water does not contain a charge, so it is a very poor conductor of electricity. The more salt that is added to the water, or the greater the concentration of ions, the better the water will conduct electricity.

  • Q:

    What is electricity made of?

    A:

    Electricity is the flow of electrons through a conductor. Materials that conduct electricity easily have a weak hold on their outermost electrons, allowing them to move easily from one atom to another. When an electron moves to an adjacent atom, it displaces another electron, and this flow is electric current.

    What is electric energy?

    A:

    Electric energy is the energy created by electrons moving through an electrical conductor. The world is made of matter. All matter contains atoms that contain electrons that are always moving. When electrons are forced down a conductive path, such as a wire, the movement produces electricity, or electric energy.

    Why is graphite a good conductor of electricity?

    A:

    Graphite is a good conductor of electricity because its electrons are delocalized or free to move around. Graphite is structured into planes with tightly bound atoms. There is a great deal of distance between planes, and they are bonded weakly together, allowing the electrons to move around.

    Does citric acid conduct electricity?

    A:

    Citric acid is not a good conductor of electricity. This is because it is an example of a weak acid, which breaks down in water quickly.
