Chemical Reactions Experiment

Chemical Reactions Experiments:

A chemical reaction is a chemical change which forms new substances and it is also known as chemical change. A chemical reaction is a process that leads to the change of one set of chemical substances to another. The chemical reactions include changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms with no change to the nucleus and can often be described by a chemical equation. During a chemical reaction the physical structure of a substance will alter. Most reactions require heat, pressure, radiation or the presence of accelerators.

The substance involved in a chemical reaction is called reactants or reagents. Chemical reactions are usually considered by a chemical change and they give up one or more products which usually have properties different from the reactants.

Chemical reactions are described with chemical equations which graphically present the starting materials, end products and sometimes middle products and reaction conditions. The general concept of a chemical reaction has been complete to non-chemical reactions between entities smaller than atoms including nuclear reactions, radioactive decays and reactions between simple particles as described by quantum field theory.

Chemical reactions are part of our daily lives example cooking in the kitchen to driving a car. This list is expected at some of the more interesting and amazing reactions that most of us have not seen or experienced.

Examples of Chemical Reactions are:

The chemical reaction H2 (g) + ½ O2 (g) ? H2O (l) describes the structure of water from its elements.

Students will learn about the scientific method and will discover chemical reactions. This activity allows students to use the scientific method to observe and identify a set of safe substances.

  1. Non-Cook Smoke Bomb Recipe

The classic smoke bomb is very easy to make. There is no possibility of accidentally setting off your smoke alarm or igniting the mixture during preparation. There is safer way to make a smoke bomb. It uses the same ingredients and produces a similar amount of smoke but it takes a bit longer to make.

Ingredients how to make the safer smoke bomb:

  • potassium nitrate
  • sugar
  • water
  • fuse
  • paper or plastic cups
  • plastic spoon
  • waxed paper

Make the Smoke Bombs

  • In a paper or plastic cup mix 3 parts of potassium nitrate with 2 parts sugar (like 3 tablespoons potassium nitrate and 2 tablespoons sugar).
  • Using your plastic spoon, stir in just enough water to make a solid paste. Continue stirring until the ingredients are evenly mixed.
  • Set lumps of the mixture (1 tablespoon) onto the waxed paper. Insert a combine into each piece.
  • Allow the smoke bombs to set up for 1-2 days. The drying time will depend on temperature and humidity. Warmer and drier is faster; cooler and limitation will take longer.
  •  Keep the smoke bombs away from too much heat or flame. The smoke bombs will be like clay when they are ready, not hard and solid.
  • Set a completed smoke bomb outside on a flameproof surface and light it.

2. Natural Toothpaste        

It’s easy to make your own natural toothpaste. These instructions are especially useful if you are trying to reduce discovery to fluoride such as for children or people who already have fluoridise. This toothpaste is sugar-free and non-toxic.

What You Need

  • sodium bicarbonate
  • salt
  • water
  • glycerine
  • peppermint oil (optional
  • Mix three parts baking soda (sodium bicarbonate) with one part table salt (sodium chloride).
  • Add three teaspoons of glycerine for every 1/4 cup of dry mixture.
  • Add enough water to make a thick paste. If required add a few drops of peppermint oil may be added to improve the taste.
  • Apply and use just as you would any other toothpaste. Store new toothpaste at room temperature in a covered container.

3. Homemade Hand Sanitizer

Some trade hand sanitizers contain ingredients as uncanny as the germs they protect you from so why not make your own hand sanitizer from ingredients you select. This is an excellent project for kids as well as adults because it includes a discussion about hygiene and disinfection. You’ll save money, protect yourself from germs, and can adjust the odour of the hand sanitizer so it doesn’t smell medical.

  • 2/3 cup 99% rubbing alcohol (isopropyl alcohol) or ethanol
  • 1/3 cup aloe Vera gel
  • 8-10 drops essential oil, optional (such as lavender, vanilla, peppermint, grapefruit)
  • bowl and spoon
  • funnel
  • recycled liquid soap or hand sanitizer bottle

Make Hand Sanitizer

Simply mix the ingredients together and then use the funnel to pour them into the bottle. Rotate the pump back onto the bottle and you’re ready to go. The active ingredient in this hand sanitizer recipe is the alcohol which needs to include at least 60% of the product in order to be an effective sanitizer.

Essential Oils in Hand Sanitizer

Thyme and clove oil have antimicrobial properties for adding smell to your hand sanitizer, the essential oil you choose may also help protect you against germs.  If you are using antimicrobial oils only use a drop or two since these oils be likely to be very powerful and might irritate your skin. Other oils such as lavender or chamomile may help pacify your skin.

4. Magnesium and Dry Ice Reaction

Magnesium ignites easily and burns very brightly. In this experiment you can see magnesium ignited in a shell of dry ice – frozen carbon dioxide. Magnesium is able to burn in carbon dioxide and nitrogen. Because of its brilliant light, it was used in early photographic flashes and it is still used in marine flares and fireworks.

5. Steel Wool & Vinegar Reaction

Soak steel wool in vinegar and watch what happens as the iron in the steel begins to react with the oxygen around it. This fun science experiment for kids is great for learning about chemical reactions.

What you’ll need:

  • Steel Wool
  • Vinegar
  • Two beakers
  • Paper or a lid (something to cover the beaker to keep the heat in)
  • Thermometer


  • Place the steel wool in a beaker.
  • Pour vinegar on to the steel wool and allow it to soak in the vinegar for around one minute.
  • Remove the steel wool and drain any overload vinegar.
  • Wrap the steel wool around the base of the thermometer and place them both in the second beaker.
  • Cover the beaker with paper or a lid to keep the heat in (makes sure you can still read the temperature on the thermometer, having a small hole in the paper or top for the thermometer to go through is a good idea).
  • Check the initial temperature and then observe it for around five minutes.


The temperature inside the beaker should gradually rise and the beaker getting foggy. When you soak the steel wool in vinegar it removes the caring shell of the steel wool and allows the iron in the steel to rust. Rusting is a chemical reaction between iron and oxygen. This chemical reaction creates heat energy which increases the temperature inside the beaker. This experiment is an example of an exothermic reaction, a chemical reaction that releases energy in the form of heat.
