Aurora watching, time-exposure image
Aurora watching. Time-exposure image of an aurora watcher by a fire, observing an auroral display in the northern hemisphere

Egg chemical reaction, 19th century
Egg chemical reaction. The reaction uses hydrochloric acid which reacts with the calcium carbonate in the egg shell to produce the white foam seen here (due to the carbon dioxide produced)

Histamine allergic reaction, diagram
Histamine allergic reaction. Diagram showing the process that leads to the release of histamine during an allergic reaction. Cells called mast cells (orange) mediate this response

Electrolysis of water. Close-up of the top of a Hoffman Voltameter used to decompose molecules of water. A power supply (not seen)

Nerve cell trauma response. Fluorescent light micrograph of a section through a spinal cord affected by multiple sclerosis (MS)

Chemical explosion. Cork exploding out of a bottle of sparkling wine. There is no wine. The cork has exploded out due to an increase in pressure due to the production of gas in a chemical reaction

Sulphuric acid added to water
Concentrated sulphuric acid (H2SO4) being added to water. The hydration reaction of sulphuric acid is highly exothermic and can cause the water to boil

Burning sugar on a spoon

Sodium burning in air. Sodium (Na) is a highly reactive metallic element from group one of the periodic table. It burns in air, reacting with atmospheric oxygen (O2) to form sodium oxide (Na2.O)

Lithium reacting with water. Lithium (Li) is a highly reactive metallic element that floats on water and reacts with it. This exothermic (heat- producing) reaction forms lithium hydroxide (LiOH)

Potassium burning in air. Potassium (K) is a soft, highly reactive, alkali metal. In air it will burn with a brilliant flame to form potassium dioxide (or potassium superoxide, KO2)

Manganese and copper voltaic cell. Copper (right) and manganese (left) half cells joined by a salt bridge. When a stick of copper (Cu)

Copper half cell. When a stick of copper (Cu) is inserted in a copper salt solution it loses electrons according to the reaction CuCu2+ + 2e

Aluminium reacting with iodine, in the presence of water, to produce aluminium iodide ((AlI3)2)

Chemistry experiment. Hand pouring vinegar onto baking soda (sodium hydrogen carbonate, NaHCO3). Vinegar is a solution of ethanoic acid (CH3COOH)
