Production[ edit ] On the industrial scale, potassium chlorate is produced by the Liebig process:

Match Background A match is a small stick of wood or strip of cardboard with a solidified mixture of flammable chemicals deposited on one end. When that end is struck on a rough surface, the friction generates enough heat to ignite the chemicals and produce a small flame.

Some matches, called strike-anywhere matches, may be ignited by striking them on any rough surface. Other matches, called safety matches, will ignite Composition of potassium chlorate when they are struck on a special rough surface containing certain chemicals.

History The first known use of matches was in during the siege of a town in northern China. Women in the town used sticks coated with a mixture of chemicals to start fires for cooking and heating, thus allowing them to conserve their limited fuel by putting the fires out between uses.

The details of this technique were subsequently lost to history. It was not until that John Walker of England invented the first friction matches. Walker's matches were ignited by drawing the heads through a folded piece of paper coated with ground glass.

He began selling them inbut they were difficult to light and were not a success.

InCharles Sauria of France developed a match that used white phosphorus. These matches were strike-anywhere matches and were much easier to ignite. Unfortunately, they were too easy to ignite and caused many unintentional fires. White phosphorus also proved to be highly toxic.

Workers in match plants who inhaled white phosphorus fumes often suffered from a horrible degeneration of the jawbones known as "phossy jaw.

In Gustaf Pasch of Sweden proposed placing some of the match's combustion ingredients on a separate striking surface, rather than incorporating them all into the match head, as an extra precaution against accidental ignition.

This idea—coupled with the discovery of less-reactive, nontoxic red phosphorus—led J. Lundstrom of Sweden to introduce safety matches in Although safety matches posed less of a hazard, many people still preferred the convenience of strike-anywhere matches, and both types continue to be used today.

The first matchbook matches were patented in the United States by Joshua Pussey in The Diamond Match Company purchased the rights to this patent in At first, these new matches were not well accepted, but when a brewing company bought 10 million matchbooks to advertise their product, sales soared.

Early match manufacturing was mainly a manual operation. Mechanization slowly took over portions of the operation until the first automatic match machine was patented by Ebenezer Beecher in Modern match manufacturing is a highly automated process using continuous-operation machines that can produce as many as 10 million matches in an eight-hour shift with only a few people to monitor the operation.

Raw Materials Woods used to make matchsticks must be porous enough to absorb various chemicals, and rigid enough to withstand the bending forces encountered when the match is struck.

They should also be straight-grained and easy to work, so that they may be readily cut into sticks. White pine and aspen are two common woods used for this purpose.

Once the matchsticks are formed, they are soaked in ammonium phosphate, which is a fire retardant.The composition of road flares.

What is in road flares? Different companies use different compositons when manufacturing road flares, so it is impossible to give a specific answer for the flare in your hand.

Experiment 6 – Percent Composition Objectives 1. To observe the techniques involved to carry out the decomposition of a chemical, potassium chlorate, KClO3, quantitatively. 2. To calculate the percentage of oxygen in potassium chlorate, KClO3, Microsoft Word - Lab6 - Percent initiativeblog.com History. Lycopodium powder is a yellow-tan dust-like powder historically used as a flash powder. Today, the principal use of the powder is to create flashes or flames that are large and impressive but relatively easy to manage safely in magic acts and for cinema and theatrical special effects.. Mixtures. Normally, flash powder mixtures are compounded to achieve a particular purpose. The Composition of Potassium Chlorate Objectives The objectives of this laboratory are: a) To experimentally determine the mass percent of oxygen in the compound potassium chlorate (KClO3) via the thermal decomposition of a sample of potassium chlorate.

To experimentally determine the mass percent of oxygen in the compound potassium chlorate (\(\ce{KClO3}\)) via the thermal decomposition of a sample of potassium chlorate. To qualitatively demonstrate that the residue resulting from the decomposition of potassium chlorate is .

Potassium chlorate is a compound containing potassium, chlorine and oxygen, with the molecular formula KClO initiativeblog.com its pure form, it is a white crystalline substance. It is the most common chlorate in industrial use. It is used as an oxidizing agent,; to prepare oxygen,; as a disinfectant,; in safety matches,; in explosives and fireworks,; in cultivation, forcing the blossoming stage of the.

THE DECOMPOSITION OF POTASSIUM CHLORATE This lab is derived almost entirely from a lab used at the United States Naval Academy PURPOSE: The purpose of this experiment is to study the decomposition of potassium chlorate.

The Decomposition of Potassium Chlorate Hypothesis: Potassium chlorate decomposes into potassium chloride and oxygen gas, which means that when the glowing splint is inserted into the test tube, the flame will have enough fuel to fully reignite the splint. When the manganese dioxide is added, this will increase the rate of the production of oxygen in the reaction, without affecting the.
