Describe an activity with diagram to illustrate that the reaction of metal Carbonate and metal bicarbonate with acid. Produce CO2 write the relevant equations of all the reactions takes place
Answers
Aim: To show acid reacts with metal carbonate to liberate carbon dioxide, Material
Required: CaCO3(marble chips), Woulfe-bottle, thistle funnel, dil. HCl, gas jar, matchbox, delivery tube bent at two right angles, lime water.
Procedure: Take two test tubes, label them as A and B. Take about 0.5 g of sodium carbonate (Na2CO3) in test tube A and about 0.5 g of sodium hydrogen carbonate (NaHCO3) in test tube B. Add about 2 mL of dilute HCl to both the test tubes. Pass the gas produced in each case through lime water (calcium hydroxide solution) as shown in below figure and record your observations. The reactions occurring in the above Activity are written as Conclusion: Metal carbonates react with dilute acids to liberate carbon dioxide. Limestone, chalk, marble are different forms of calcium carbonate. All metal carbonates and hydrogen carbonates react with acids to form
