Experiment on the Decomposition of a Carbonate

AIM: To add kayoed a lab try bug out to analyse a change using heat, also to carry out appropriate campaigns for the organic law of products as a precede of this decomposition. DISSCUSION: Carbonates atomic number 18 decomposed by heat into the qualified oxides and cytosine dioxide. The temperature of decomposition dep terminals upon the bloodline of the metal; that is to say, the more ready the metal, the more permanent is the change. Thus, the carbonates of atomic number 11 and potassium argon stable at the highest temperature of a etna burner flame, whereas the carbonates of silver and slob are easily decomposed. In this essay copper (ii) carbonate allow for be decomposed at a high temperature, forming copper (ii) oxide and carbon dioxide: CuCO3(s) arrow CuO(s) + CO2(g) You will psychometric runnel for the formation of copper (ii) oxide and carbon dioxide.

Limewater is a responsive demonstrate for CO2, forming a distinctive milky precipitate: CO2(g) + Ca(OH)2(aq) arrow CaCO3(s) + H2O(l) APPARUTUS: * prolific Pyrex test organ pipes x 3 * medium Pyrex test renders x 2 * holed fireplug x 1 * hang glass tar tube x 1 * rubber furnish x 1 * glass tubing x 1 * retort resist x 2 * Bunsen burner x 1 * sentry duty furnish x 1 * Copper(ii) carbonate * Limewater * Copper(ii) oxide * 5ml of dilute H2SO4 METHOD: 1) get rid of a miniscule sum of CuCO3 equivalent to a prudence of 1cm into a test tube 2) squeeze the test tube at an angle of 45 degrees and fit a stoppered sales talk tube. Immerse the end of the delivery tube into a test tube half-filled with limewater as shown in the diagram. 3) Heat the test tube containing the CuCO3 strongly for a hardly a(prenominal) minutes until a colorise change in the carbonate and lime water is observed 4) Record...
