Decomposição térmica do bicarbonato de sódio: do processo Solvay ao diagrama tipo Ellingham
A didactic experiment based on the thermal decomposition of sodium bicarbonate using a reagent found in the marketplace is proposed. The reaction products are identified by qualitative tests and stoichiometric calculations. The thermal stability of carbonates and the influence of lattice energies ar...
