Decomposition of nitrates a level

WebThis misconception is due to learners associating the higher charge density in the metal ion with a stronger attraction between the ion and the carbonate, and so requiring more energy to break apart. Some learners may find the actual explanation initially counterintuitive. WebStudents should find that sodium and potassium carbonates give no carbon dioxide or any other sign that decomposition has taken place, even after prolonged heating. Those …
