What two chemicals can you mix to make fire?

Answered by Phillip Nicastro

When it comes to creating fire through chemical reactions, there are several combinations that can be used. However, it is important to note that working with fire and chemicals can be dangerous if not done properly. Safety precautions should always be followed, and it is advisable to have proper training and supervision when conducting such experiments.

One common combination to create fire involves the use of potassium chlorate and table sugar, with sulfuric acid acting as a catalyst. Potassium chlorate (KClO3) is a strong oxidizer, meaning it provides oxygen to support combustion. Table sugar, or sucrose (C12H22O11), is a readily available source of fuel. When these two substances are mixed together and a small amount of sulfuric acid (H2SO4) is added, a highly exothermic reaction occurs.

The reaction between potassium chlorate and sugar is known as a redox reaction, where the sugar is oxidized and the potassium chlorate is reduced. The sulfuric acid acts as a catalyst, speeding up the reaction. As a result, a significant amount of heat energy is released, leading to a rapid increase in temperature. This heat energy is responsible for the spectacular purplish flame observed during the reaction.

The reaction can be summarized by the following equation:

10KClO3 + C12H22O11 + 8H2SO4 → 5K2SO4 + 12H2O + 12CO2 + 8SO2

In this reaction, potassium chlorate is reduced to potassium sulfate (K2SO4), and the sugar is oxidized to carbon dioxide (CO2) and water (H2O). Sulfur dioxide (SO2) is also produced as a byproduct.

It is worth noting that this reaction is highly exothermic and can be dangerous if not handled properly. The release of large quantities of heat energy can lead to the generation of a great deal of smoke. Additionally, the reaction may produce toxic gases, such as sulfur dioxide. Therefore, it is crucial to perform this reaction in a well-ventilated area and take necessary safety precautions, such as wearing protective eyewear, gloves, and a lab coat.

Mixing potassium chlorate and table sugar, with the addition of sulfuric acid as a catalyst, can result in a violent reaction that releases large quantities of heat energy, a spectacular purplish flame, and a great deal of smoke. It is important to exercise caution and follow safety guidelines when working with such chemicals to prevent accidents and ensure personal safety.
