Decomposition Reactions

Flashcards about types of decomposition reactions

Thermal decomposition reaction (Thermolysis)

A chemical reaction where a single substance breaks into two or more simple substances when heated.

Electrolytic decomposition reaction (Electrolysis)

Decomposition reaction that occurs when electric current is passed through an aqueous solution of a compound.

Thermal Decomposition of Ferrous Sulphate

Green crystals of ferrous sulphate lose water on heating, resulting in a change in color before further decomposition into ferric oxide, sulphur dioxide, and sulphur trioxide.

Decomposition of Calcium Carbonate

Calcium carbonate (limestone) decomposes into calcium oxide (quick lime) and carbon dioxide when heated.

Decomposition of Potassium Chlorate

Potassium chlorate decomposes into potassium chloride and oxygen when heated strongly, often used for oxygen preparation.

Decomposition of Ferric Hydroxide

Ferric hydroxide undergoes decomposition to give ferric oxide and water molecules upon heating.

Decomposition of Hydrated Oxalic Acid

Hydrated oxalic acid decomposes into oxalic acid and water when heated.
