Carbinates Study Paper

DISSCUSION: Carbonates are decomposed by temperature into the related oxides and carbon dioxide. The temperature of decomposition is dependent upon the activity of the metal; frankly, the more effective the metal, the more steady is the carbonate. Thus, the carbonates of sodium and potassium will be stable on the highest heat of a Bunsen burner fire, whereas the carbonates of silver and copper are decomposed. From this experiment birdwatcher (ii) carbonate will be decomposed at a higher temperature, developing copper (ii) oxide and carbon dioxide: CuCO3(s) arrow CuO(s) + CO2(g)

You will evaluation for the formation of water piping (ii) oxide and carbon dioxide. Limewater can be described as sensitive test out for LASER, forming an exclusive milky precipitate: CO2(g) & Ca(OH)2(aq) arrow CaCO3(s) + H2O(l)

Calcium supplements carbonate is definitely strongly heated up until it goes through thermal decomposition to form calcium supplement oxide and carbon dioxide CaCO3 CaO + CO2

Different metal carbonates decompose in the same way. Here are the equations to get the heat decomposition of copper carbonate: copper carbonate copper o2 + carbon

CuCO3 CuO + CO2

Notice that in both illustrations the products can be a metal o2 and carbon dioxide. The co2 gas can be detected using limewater. Limewater turns cloudy white the moment carbon dioxide is bubbled through it. Precious metals high up in the reactivity series - such as calcium -- have carbonates that need a lot of energy to decompose all of them. Metals low down in the reactivity series -- such as water piping - have carbonates which have been easily decomposed. This is why birdwatcher carbonate can often be used in school to demonstrate these reactions. It is easily decomposed, and its particular colour transform, from green copper carbonate to black copper o2, is easy to find out

Copper Carbonate (CuCO3) is heated up so that a decomposition effect occurs, with the products staying Copper (II) Oxide (CuO) and Co2 (CO2). The chemical formulation is: CuCO3 --> CuO + CO2. If correct apparatus is to establish, the co2 should...
