Lithium carbonate decomposes similar to MgCO3 , Li 2 CO 3 → Li 2 O + CO 2. the caesium and barium carbonates pass a standard 1000 h damp heat test, with >95% of their initial performance maintained. (a) MgCO3 (b) CaCO3 (c) SrCO3 (d) BaCO3, Thermal stability  size of the cation in carbonates, increasing order of cationic size in alkaline earth metal is, Therefore the most thermal stable carbonates are of Barium. An exhaustive E-learning program for the complete preparation of JEE Main.. The effect of heat on the Group 2 The term "thermal decomposition" describes splitting up a compound by heating it. The carbonates of group-2 metals and that of lithium decompose on heating, forming an oxide and carbon dioxide . However, carbonate of lithium, when heated, decomposes to form lithium oxide. Group 2: Alkaline Earth Metals and Carbonates (XCO 3). 11. Vipin Sharma Biology Blogs for more information regarding every national level competitive exam in which biology is a part . Solubilities of alkaline earth metal carbonates in water and aqueous solutions are of interest in many areas such as biology, geology, hydrology, medicine, and environmental sciences. Describe the thermal stability of carbonates of alkali and alkaline earth metals. Thermal stability of alkaline earth metal carbonates decreases in the order (A) BaCO3 > SrCO3 > CaCO3 > MgCO3 (B) BaCO3 > SrCO3 > MgCO3 > CaCO3 (C) Ca From Li to Cs, due to larger ion size, hydration enthalpy decreases. Which of the following is most soluble in water? All the carbonates in this group undergo thermal decomposition to the metal oxide and carbon dioxide gas. Compare the solubility and thermal stability of the following compounds of the alkali metals with those of the alkaline earth metals. Ans. Alkaline Earth Metals(Group 2) Dr. S. S. Tripathy 10. [ M = Be, Mg, Ca, Sr, Ba] (b) Carbonates-Alkaline earth metal carbonates decompose on heating gives carbon dioxide and oxide. Carbonates of alkali metals are soluble in water with the exception of Li2CO 3. Hydration Energy and Electrical conductivity in aq. Because beryllium and its salts are toxic, however, BeCO 3 cannot be used as an antacid.
