Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust o…
What is the chemistry of lighting a match?
Learn about the chemistry of lighting a match. The head of a match uses antimony trisulfide for fuel. Potassium chlorate helps that fuel burn and is basically the key to ignition, while ammonium phosphate prevents the match from smoking too much when it's extinguished.
What is the chemical reaction in a match?
When you strike a match the red phosphorus is converted to white phosphorus for a fraction of a second, just enough to cause a spark of heat by reacting with oxygen in the surrounding air. This heat then ignites the first chemical on our journey – potassium chlorate. What chemical is used in match heads?
What happens when you light a match?
Striking A Match. When a match is lit, potassium, chlorine, phosphorus, and sulfur react and cause a combustion, which produces light and heat. This chemical reaction is exergonic because it releases energy and exothermic because it releases heat.
How does a matchstick light a match?
When we rub a matchstick against the rough surface of a matchbox, the head of the matchstick rubs against the side of the matchbox that is hotter. The heat burning the chemicals on the head of the matchstick causes it to light up. ⟵ How Large Should Your Chandelier Be?
What type of chemical reaction is lighting a match?
combustion reactionA familiar example of a combustion reaction is a lighted match. When a match is struck, friction heats the head to a temperature at which the chemicals react and generate more heat than can escape into the air, and they burn with a flame.
Is lighting up a match a chemical reaction?
When a match burns, it undergoes a chemical change. Matches use sulfur, phosphate and a friction agent held together by a binding agent. With a match, heat ignites the phosphorous on the head of the match. To keep the fire going, the match needs more oxygen than is available from the air alone.
What is the chemical equation for matches?
The match head contains a mixture of two chemicals, phosphorus sesquisulfide P4S3 and potassium chlorate(v), KClO3.
What is the process of lighting a match?
To light a match, first grip the middle of the match between your thumb and index finger. Then, press the head of the match against the striker on the matchbox. Finally, quickly drag the match head across the striker to light the match.
What type of change occurs when a match is burnt?
A burning match is a chemical change.
Why is lighting a match a spontaneous reaction?
Spontaneous reactions do not normally take place (at room temperature and pressure), because of the activation energy barrier. Adding extra energy from outside the system, such as the heat energy from a match, starts most spontaneous reactions, which then proceed naturally.
What are the chemical properties of a match?
Modern safety matches usually have antimony sulfide, oxidizing agents such as potassium chlorate, and sulfur or charcoal in the heads, and red phosphorus in the striking surface. Nonsafety matches usually have phosphorus sesquisulfide in the heads.
What gas does a burning match release?
oxygen gasThe heat from the friction also causes the oxidizing agent to produce oxygen gas, igniting the small amount of white phosphorous. Once ignited, the oxygen gas fuels the flame while the rest of the sulfur catches on fire.
What's on the end of a matchstick?
Phosphorous sulfide is the chemical compound that ignites match heads. It's found in the heads of strike-anywhere matches and in the strip on the side of safety match boxes.
Why is burning a match a chemical change?
When you rub the match on the box, you get friction, which means you get heat. This heat causes a small amount of the red phosphorus chain to be broken apart. When that happens, some of the red phosphorous changes into another chemical called “white phosphorus”.
What type of energy is lighting a match?
Chemical energy** A matchstick has a lot of chemical energy stored in it. When the match is struck, it burns and the chemical energy in it produces heat energy and light energy.

Because of the “SAFETY” clause the match head will not catch fire like an incendiary phosphorus device, it requires serious heat on a small area to cause an ignition point much like our motor spirit.
What is the star of the show when it comes to igniting a match?
Phosphorus is the star of the show when it comes to igniting a match. And like many Hollywood starlets, it's unstable, sensitive and volatile. This is especially true for white phosphorus, which can ignite spontaneously in the air and was used in early matches.
What is the match head made of?
The striking surface is composed of typically powdered glass, red phosphorus, neutralizer, carbon black and binder; and the match head is typically composed of potassium chlorate, with a little sulfur and starch, a neutraliz er, siliceous filler, diatomite and glue.
What are the ingredients in a match?
Specifically, these ingredients are an igniter, a fuel and an oxidizer.
What is the key to ignition?
The head of a match uses antimony trisulfide for fuel. Potassium chlorate helps that fuel burn and is basically the key to ignition, while ammonium phosphate prevents the match from smoking too much when it's extinguished. Wax helps the flame travel down the matchstick and glue holds all the stuff together. The dye-- well, that just makes it look pretty. On the striking surface, there's powdered glass for friction and red phosphorus to ignite the flame.#N#Now, the fun stuff-- striking a match against the powdered glass on the matchbox creates friction. Heat from this friction converts the red phosphorus into white phosphorus. That white phosphorus is extremely volatile and reacts with oxygen in the air, causing it to ignite. All this heat ignites the potassium chlorate, creating the flame you see here.#N#Oxidizers, like potassium chlorate , help fuels burn by giving them more oxygen. This oxygen combines with antimony trisulfide to produce a long-lasting flame so you have enough time to light a candle. The whole thing is coated with paraffin wax, which helps the flame travel down the match. Just don't burn the house down.#N#As antimony oxidizes, sulfur oxides form, creating that burnt-match scent. The smoke you're seeing is actually tiny unburned particles resulting from an incomplete combustion. Individually, they're a little bit too small to see but grouped together, they form smoke. There's also some water vapor in there.#N#By the way, all the stuff that we're explaining in 90 seconds, it all happens within tenths of a second. Chemistry's fast.
What is the purpose of wax on matchsticks?
Wax helps the flame travel down the matchstick and glue holds all the stuff together. The dye-- well, that just makes it look pretty. On the striking surface, there's powdered glass for friction and red phosphorus to ignite the flame.
