Thermal Decomposition of Metal carbonates

The aim of this experiment is to determine the magnitude of the contradictivity serial upshot by investigating the thermal breakdown of surface carbonates. scheme When a coat is thermally decomposed the bond between the alloy and its carbonate (carbon and type O) is removed and the carbonate is released as cerbon dioxide. The responsiveness series determines how degraded this opposeion occurs. The responsiveness series is the tar choose alloys in the day-to-day table. The most reactive metals argon set(p) at the crimp of the reactivity series. The least reactive materials ar placed at the bottom of the reactivity series. From preliminary work on that I hit already done I sleep together that Potassium and sodium are the most reactive metals, and that lucky and platinum are the least reactive metals. To determine the order of how reactive a metal is and where to place it in the reactivity series you take up to come over how the metal reacts to: ? Oxygen (air) ? Wate r ? Acid When metals are heated they react with type O in the air. As the metal is heated it reacts with the oxygen to form an oxide. The most reactive metals such as super acid and sodium burn brightly as they are heated. The piddling reactive metals do not burn brightly, and take wide to form their oxide. With some metals there is no reaction at all.

These are the metals at the bottom of the reactivity series, such as gold. Also the most reactive metals form their oxide much sprightly than the less reactive metals. This type of reaction is called an oxidation reaction, because the metal gains an oxygen. The formula for the reaction with air is: metall! ic element + Oxygen = Metal Oxide Metals potful also be placed in water to see how they react. Again the extremely reactive metals potassium...
