Which metal carbonates decompose on heating




















Get iOS App. Metal carbonates decompose on heating to give metal oxide and carbon dioxide. The s-Block Elements Report Error. Solution: As the electropositive character increases down the group, the stability of the carbonates increases. Questions from The s-Block Elements. Which alkali metal during flame test will show colour corresponding to maximum wavelength?

AIIMS Which one of the following has maximum lattice energy? AMU The halide of which alkaline earth metal is covalent and soluble in organic solvents? KEAM Which of the following is the weakest base? In which of the following the hydration energy is higher than the lattice energy? The decomposition temperature is the lowest for AMU If we take the two examples above, sodium is a very reactive metal. This means that sodium carbonate is very stable and requires a high temperature to decompose.

However, copper is a very unreactive metal, which is why it is useful for making water pipes, and so copper II carbonate is quite unstable and decomposes at a relatively low temperature. The stability of the metal carbonates can be related to the reactivity series of metals. The higher up the series a metal is, the more reactive the metal is and so the more stable the metal carbonate is. The stability of the metal carbonates can be measured by heating the carbonate and bubbling the carbon dioxide given off through limewater.
