Polariser is frequently a specially made prism from crystal of Iceland Spar (form of calcium carbonate), also known as Nicol’s prism. It can also be a small plate of tourmaline.
Ideal solution is a solution in which solvent-solvent and solvent-solute interactions are identical, so that properties such as volume and enthalpy are exactly additive. Ideal solutions follow Raoult’s law, which states that the vapour pressure pi of component i is pi = xi pi*, where xi is the mole fraction of component i and pi* the vapour pressure of the pure substance i.
Inert electrode is an electrode that serves only as a source or sink for electrons without playing a chemical role in the electrode reaction. Precious metals, mercury, and carbon are typically used as inert electrodes. The inert nature of the electrode can sometimes be questioned. While the electrode may not take part in the reaction as a reactant or product, it still can act as an electrocatalyst.
Polycondensational polymers are compounds which are obtained by condensation polymerization with successive repetitions of the condensation reaction.
Polyvalent element is a molecule which having more than one valence, for example oxygen is a divalent in H2O, nitrogen is a trivalent in NH3, carbon is a tetravalent in methane (CH4).
Iodine was discovered by Bernard Courtois (France) in 1811. The origin of the name comes from the Greek word iodes meaning violet. It is shiny, black, non-metallic solid with characteristic odour. Sublimes easily and as a gas it is violet and intensely irritating to the eyes, nose and throat. Iodine occurs on land and in the sea in sodium and potassium compounds. Required in small amounts by humans. Once used as an antiseptic, but no longer due to its poisonous nature.
Potassium fertilizers are compounds of potassium used as an artificial manure e.g. potassium-chloride, potassium-sulphate, potassium-magnesium-sulphate, and ashes formed after wood burns out.
Potassium glass is a type of glass produced from potassium silicates and calcium with potassium carbonate. It dissolves harder than regular glass and it is used in production of chemical vessels.
