  1. Table Salt Electricity Submitted by: Niya Williams Teacher: Mesiha Plummer Grade: Seven grade

  2. My purpose for choosing this experiment is to learn more about electrons, protons, ions, and electricity. I also will like to learn more about electrolytic cell and if salt can be use for electricity. PURPOSE

  3. Science Question • Can table salt be use for electricity.

  4. Hypothesis • What if then the table salt had an negative charge and not a positive charge.

  5. I was always wanted to know if table salt can produce electric currents. . Reasons for choosing this project.

  6. Description I will identify, understand and study more about electricity cells, electrolysis of water and brine.

  7. ELECTROLYTES

  8. PROCEDURE 1. Tape the three batteries together with the positive end of one touching the negative end of the other. 2.Combine the salt and water in the bowl. Stir well. 3. Measure and cut a strip of aluminum foil 4 inches x 12 inches long. 4. Fold the foil strip length wise four times so that the strip is ¼ inches wide and 12 inches long. 5. Strand the flat, negative end of the connected batteries in the bowl of salty water. 6. Wrap one end of the foil strip around the metal base of the flashlight bulb. 7. Hold the foil strip tightly around the base and press it against the raised, positive end of the connected batteries. 8. Lay the free end of the foil strip under the surface of the salty water in the bowl so that it is near but not touching the connected batteries.

  9. RESULT THE LIGHT BULB GLOWS

  10. WHY IT HAPPEN? The bulb glows because as the electric current passes through the filament heats up and gives off light. The electrons do not flow spontaneously. They must be caused to flow by an electric force from the battery. The negative end of the battery repels electrons, and the positive end of the battery draws electrons towards it. Electrons do not flow out the cathode {negative terminal} of the battery and swim through the solution to the aluminum foil strip attached to the anode {positive terminal}. Instead, at the negative terminal, cations {positive particles} in the solution accept electrons; at the positive terminal, anions {negative particles} give up electrons. The space between the foil strip and the battery is "bridged" as the ions in solution remove electrons from one side and add electrons to the opposite side of the gap.

  11. DICTIONARY WEDSTER 1. Anion are negative chemical particles. 2. Anode are conductor connected to, or the positive terminal of a battery 3. Cathode are conductor connected to, or the negative terminal of a battery. 4. Cation are positive chemical particle. 5. Electric currents are flow of electric charges. 6. Electrolysis are process by which an electric current is used to cause a chemical change. 7. Electrolyte are substance that conducts an electric current in solution or in a molten state. 8. Ionic conduction are electric current produced by the movement of ions in a solution. 9. Ions are charged particles in a solution. 10. Metallic conduction are electric current produced by a flow of electrons in metal.

  13. I learn that salty water can be use as a solution for electricity and how electric current flows, then gives off light. WHAT I HAVE LEARN
