Core & Ext. Metals: Displacement Rxns & Stability of Compounds
Slide 33 of 42
Summary
The more reactive the metal, the stronger the tendency for it to be in the ionic state.
For instance, it will displace the ion of a less reactive metal from a salt solution converting it into an atom, while itself changing from the atomic state to an ionic state.
It will also displace the ion of a less reactive metal from the oxide of the metal converting into an atom while itself changing from the atomic state to an ionic state (in the oxide into which it transforms).
The more reactive the metal the more stable its compound to heat.
–If unstable, the hydroxide decomposes to the oxide and water.
–The nitrates either to nitrite and oxygen or oxide, nitrogen dioxide and oxygen.
–Carbonates to oxide and carbon dioxide.
