  • Lab Technician adding universal indicator to water after Potassium previously added to see reaction.  Water turns colour and chart is used as reference -  Potassium reacting with water. Potassium (K) is a highly reactive metallic element. On contact with water it undergoes an exothermic (heat-producing) reaction to form potassium hydroxide (KOH) and hydrogen gas (H2).

  • Lab Technician adding Potassium to water to see reaction -  Potassium reacting with water. Potassium (K) is a highly reactive metallic element. On contact with water it undergoes an exothermic (heat-producing) reaction to form potassium hydroxide (KOH) and hydrogen gas (H2). The purple flame is produced as the high temperature causes the hydrogen gas to ignite. The purple colour is produced by small amounts of vaporised potassium in the flame.

  • Hydrated Copper Sulphate in left hand tube (blue) and un-hydrated copper sulphate in right hand tube (white) Adding water to de-hydrated copper sulphate. Water being added to a test tube containing de-hydrated (anhydrous) copper (II) sulphate (CuSO4, white). The copper (II) sulphate forms hydration bonds with the water in an exothermic (heat-producing) reaction, resulting in hydrated copper (II) sulphate (blue).

  • Fat test. Test tube containing a fatty emulsion (suspension of one liquid in another) floating on top of water. This test is used to identify fats in food. A sample of a food stuff is mixed with bromine and added to water. If the emulsion floats on top of the water, fat is present.

  • Experiement - Lab Technician dropping Universal Indicator into water with Lithiumin previously added.  Water Turns blue and is compated to chart for reference.  Lithium (Li) is a highly reactive metallic element. It is light enough to float on water, with which it reacts violently to produce hydrogen (H2) gas and lithium hydroxide (LiOH). Bubbles of H2 can be seen around the piece of metal
