Thermal stability size of the cation in carbonates. The thermal stability of carbonates increases with the increasing basic strength of metal hydroxides on moving down the group.Thus the order is . This behavior is expected by considering the fact that thermal stability of alkaline earth carbonate salts notoriously decreases as the radius of the cation is reduced. Therefore the most thermal stable carbonates are of Barium. MgCO 3 < CaCO 3 < SrCO 3 < BaCO 3 Down the group thermal stability of nitrates increases. NCERT RD Sharma Cengage … Whereas bicarbonates give carbonate, water and carbon dioxide. Thermal stability: * Carbonates are decomposed to carbon dioxide and oxide upon heating. All the carbonates in this group undergo thermal decomposition to the metal oxide and carbon dioxide gas. Yes. The salts containing one or more atoms of oxygen such as oxides, hydroxides, carbonates, bicarbonates, nitrites, nitrates, sulphates, oxalates and phosphates are called oxo salts. Maths. NCERT P Bahadur IIT-JEE Previous Year Narendra Awasthi MS Chauhan. Thermal stability of alkaline earth metal carbonates decreases in the order (A) BaCO3 > SrCO3 > CaCO3 > MgCO3 (B) BaCO3 > SrCO3 > MgCO3 > CaCO3 (C) Ca. In addition to alkali metal impurities, coal often contains substantial amounts of alkaline earth metals in the form of carbonate minerals such as calcite (CaC03) and dolomite (CaCC>3 gC03). DOI: 10.5772/16431. The carbonates of alkaline earth metals can be regarded as salts of weak carbonic acid (H2CO3) and metal hydroxide, M (OH)2. So it does not decomposes furthermore when heat is supplied. (a) MgCO3 (b) CaCO3 (c) SrCO3 (d) BeCO3. Does magnesium carbonate decompose when heated? Lattice energy considerations also indicate strong alkali carbonate instability induced by Mg incorporation for its cation size (0.130 nm) being much smaller than the counterpart carbonate anion (0.185 nm) [17] .
