# Salt Water

We all use different forms of battery in our everyday live. These batteries come in different forms and size along with power and energy it can produce? But what if we ever run out of batteries? This science experiments will teach how to produce electricity with ‘Salt’- one of the common household component and water.

### Objective:

This experiment mainly aims at exploring components of the battery and focuses primarily on the areas of conductivity in a battery and its effects on the generation of electricity. You may have already seen the usage of battery in various areas. Here you can explore in detail.

### Materials Required

• Salt
• Copper-Coated wire
• Tape
• Zinc Coated Nail
• Graph, Paper
• Two insulated wires with alligator clips on both the ends
• Voltameter
• Small Glass Jar
• Water
• Measuring Spoons

### Procedure

• First, prepare a saltwater solution. Take a small amount water in a jar and mix it well along with a two or three pinches of salt.
• Now place a zinc-coated nail in the solution.
• Tape the nail to the one end of the jar. It should be to the -ve electrode.
• Attach an alligator clip of one wire to one edge of the coated zinc wire that is falling free outside the solution.
• Alligator clip can be removed by squeezing.
• Now, attach the alligator clip of one end of the wire to the -ve terminal of the volt meter.
• Connect the copper coated nail to the +ve terminal of the volt meter. Â To do this, repeat Â the same procedure that has been specified above for zinc coated nail.
• Observe the dial of a voltmeter and pen down the readings that determines the amount of current flow between the 2 electrodes.
• Once again add a pinch of salt and check the readings. Repeat the same procedure to pen down more readings.

### Result

Check out the difference in the readings. It can be plotted in a graph for reference. In a graph there exist a point where the current stops increasing.
