Thermal Stability Flashcards
1
Q
Thermal stability
A
How stable a compound is when heated
2
Q
Factors that effect
A
Gr2 have an2+ ion
Small ionic radius
Complex carbonate ions
3
Q
Which compounds thermally decompose?
A
Lithium ( charge density for gr1 too low)
Gr2 carbonates
4
Q
Gr2 Nitrates and carbonates
A
The stability of NO3- and CO32- is affected by the smaller more highly charged ions as they have a high charge density and a complex anion.
POS charge attracts the ion so there is enough energy for the product to be lost before attraction of charge is separated
5
Q
Gr2 Cabonates
A
More difficult down group cation radii increases
6
Q
What do gr2 carbonates decompose into?
A
Metal oxides and CO2
