Endothermic And Exothermic Reaction Graphs Of Polynomial Functions

A solution of aluminium is conditioned with acetate buffer and an excess of sodium and potassium ions. Titration with sodium or potassium fluoride yields the exothermic precipitation of an insoluble alumino-fluoride salt. Anode: O -> 1/2O + 2e. Cathode: HO + 2e -> H + O. Net Reaction: HO -> H + 1/2O. Electrolysis of water at 298 K (25 °C) requires 285.83 kJ of energy in order to occur, and the reaction is increasingly endothermic with increasing temperature. [Read More]
