For an ionic substance to conduct electricity, its ions must be free to move. As such, it must be in a molten state or in solution. Solid ionic substances will not be able to conduct electricity.

Increased temperature will favour the backward (endothermic reaction.) Any change imposed on the system will be counteracted by a response which reverses the change, i.e. shift the equilibrium in the dire...

Add to the unknown solution dilute nitric acid, then add silver nitrate solution. If Chloride, bromide or iodide ions are present then a white, cream and yellow precipitate will form respectively of silve...

Decomposition of Hydorgen peroxide solution, H₂O₂, using Manganese (IV) oxide as a catalyst. Effervescence is observed as the oxygen gas is evolved and the gas can be collected by di...
