Q:

What are 5 household chemical reactions?

A:

Five chemical reactions that can be done at home are an erupting volcano, melting a foam cup with acetone, pouring vinegar on rocks to test for calcium carbonate, destructing black ink and rusting steel wool. These little experiments are simple and use common household products.

Erupting volcanoes are fun and easy. In a tall jar, add a mixture of 1/4 cup water, 1/4 cup baking soda, three tablespoons of dish soap and a couple drops of food coloring, then close the jar with a lid. Set the jar in a deep tray and, if desired, build a volcano around the jar using dirt or plaster of Paris. Unscrew the lid, and pour in 1/4 cup vinegar, and watch the volcano erupt.

Melting a foam cup in acetone, such as nail polish remover, can be done by placing the foam cup upside in a bowl with 1/2 inch of acetone.

Placing different rocks in small cups and pouring vinegar on them to see if they fizzle tells if they have calcium carbonate.

Another fun, easy experiment is done by drawing a small picture on a strip of coffee filter using a black pen. Dip the filter just below the drawing in water and watch the water diffuse up the filter, stretching the image and then separating the black ink into different colors.

Lastly, place one piece of steel wool in a clear glass completely submerged in water and another piece in a glass but only with enough water to cover half the steel wool. Wait a few days and see that the mix of oxygen and water turned the second piece rusty.
