[ ���{,kA|���[(, Aim: To investigate the rate of reaction between Calcium Carbonate (CaCo3) and hydrochloric acid (HCl) by changing the molarity of the acid and measuring how much Carbon Dioxide (Co2) is produced.

This is an example of a precipitation reaction: Reaction 1: CaCl2(aq) + Na2CO3(aq) Æ CaCO3(s) + 2NaCl(aq) We will then add aqueous sulfuric acid (H2SO4) to the products of Reaction 1 to form calcium sulfate (CaSO4), water, and carbon dioxide (CO2). Simply add an acid to the solution and if bubbles of carbon dioxide are given off, the solution contains carbonate ions. BT This type of reaction can also be used to test unknown solutions for the presence of carbonate (CO3–) ions. 179 0 obj <> endobj When acids react with metal hydroxides (commonly known as alkalis), a salt and water are made. It can be detected by passing the gas through limewater, which will go cloudy. (NaCl). Also note that the reaction of metal hydroxides with acids is exothermic (ie heat energy is given out). [ (P) 40 (age 1 of 32) ] TJ nitric acid + lithium hydroxide → lithium nitrate + water. Also, the reaction of metal carbonates with acids is exothermic (ie heat energy is given out). Simply add a solution of sodium carbonate to the solution and if carbon dioxide gas is given off, the solution is acidic. %%EOF Sulfuric acid react with calcium carbonate H 2 SO 4 + CaCO 3 → CaSO 4 + CO 2 + H 2 O [ Check the balance ] Sulfuric acid react with calcium carbonate to produce calcium sulfate, carbon dioxide and … acid + metal carbonate → salt + water + carbon dioxide, sulfuric acid + iron(II) carbonate → iron(II) sulfate + water + carbon dioxide. 0000001389 00000 n Q When acids react with carbonates, such as calcium carbonate (found in chalk, limestone and marble), a salt, water and carbon dioxide are made. /Fabc11 9 Tf Simply add an acid to the solution and if bubbles of carbon dioxide are given off, the solution contains carbonate ions. ���r�i�B ?n�?I���!��C�R� ��ϝ��aI.
