TRANSCRIPT

• There are two types of matches that we can find out in the market: safety matches and the “strike anywhere” matches.

Safety Matches

• Potassium chlorate + phosphorus agent+ sulfur agent

Strike-anywhere Matches

• Potassium chlorate + phosphorus agent+ sulfur agent

• The red phosphorus is found at the side of the box where the matches come in. On the side of the box you will also find binder and powder glass.

• The potassium chlorate and sulfur are found at the head of the match.

• The head of the “strike anywhere” match contains potassium chlorate and tetraphosphorus sulfide, glass and binder.

• Safety match chemical equation – 3KClO3 + Sb2S3 ----> 3KCl + Sb2O3 + 3SO2.

• Strike anywhere match chemical equation– 16KClO3 + 3P4S3 ----> 16KCl + 3P4O10 + 9SO2
