thermal decomposition of group 1 nitrates

GCSE. CatusStarbright. Answers are included. All the nitrates in this Group undergo thermal decomposition to give the metal oxide, nitrogen dioxide and oxygen. The hydroxides of the Group II metals, which may be used in thermochemical water-splitting cycles, have been investigated thermoanalytically. There is also a resource which goes through the qualitative observations associated with thermal decomposition of the carbonates and nitrates (what’s observed e.g limewater goes cloudy, brown gas of Nitrogen dioxide etc). Strontium Nitrate Strontium has a greater ionic radius than beryllium since it is affected by more electrostatic forces of attraction due to more protons in its nucleus and more electron shells. In Group 1, lithium carbonate behaves in the same way, producing lithium oxide and carbon dioxide: \[ Li_2CO_3 (s) \rightarrow Li_2O(s) + CO_2 \] The rest of the Group 1 carbonates do not decompose at laboratory temperatures, although at higher temperatures this becomes possible. Group 2 metals (like magnesium) give NO2 and O2 as well as the metal oxide: 2 Mg(NO3)2 (s) --> 2 MgO (s) + 4 NO2 (g) + O2 (g) Group 1 metals are different. Start studying Chemistry - Thermal Decomposition of Metal Nitrates, Carbonates and Hydroxides. The decomposition of metal nitrates in air has been systematically studied by thermogravimetry. Answer Save. Lithium Nitrate decomposes in the same way as Group 2 Nitrates. Some compounds break down when heated, forming two or more products from one reactant. The group 1 cation except Li can form a stable lattice with the large nitrite ion, but group 2 cations are smaller due to higher charge density, and the lattice is unstable. 806 8067 22 Registered Office: International House, Queens Road, Brighton, BN1 3XE, Article by TSR User on Wednesday 15 February 2017. Calcium ion also has a smaller radius and so a higher charge density giving it a greater polarising power allowing it to distort the bonding If decomposition is sufficiently exothermic, a positive feedback … Lithium acts similar: This type of reaction is called thermal decomposition. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition. aramis8, Started by: As you go down the Group, the carbonates have to be heated more strongly before they will decompose.
