Question

Describe an activity with diagram to show that the reaction of metal carbonates and metal hydrogen carbonates with acids produce carbon dioxide. Also, write the necessary chemical reactions.​

Answer 1

Answer:  

AIM :  

To show Acid responds with metal carbonate to free carbon dioxide.  

MATERIALS REQUIRED :  

• CaCO3 (marble chips), Woulfe-bottle, thorn pipe, weaken HCl, gas container,  

• matchbox, conveyance tube bowed at two right edges, lime water.  

Method :  

• Step through two exam cylinder and level them as An and  Take a measure of sodium carbonate (Na2CO3) in test tube An and than take a similar measure of Sodium Hydrogen Carbonate (NaHCO3) in test tube B.  

• Include around 2 ml of weaken HCl to both the test tubes.  Pass the gas delivered for each situation through lime water (calcium hydroxide arrangement) as appeared in chart gave previously.  

• Presently, record your perceptions.  

Reaction

CaCo3 + 2HCl - > CaCl2 + H2O + CO2  

Ca(OH)2 + CO2 - > CaCO3 + H20.  

Conclusion

• Metal carbonates respond with weaken acids to free carbon dioxide.  

• Limestone, chalk, marble are various types of calcium carbonate.  

• Every single metal carbonate and hydrogen  carbonates respond with acids to frame relating salts, water and carbon dioxide.
