What happen to all Gp2 carbonates?
Undergo thermal decomposition to produce metal oxide and carbon dioxide gas
What compounds all undergo thermal decomposition?
Gp2 carbonates
What is thermal decomposition?
Splitting a compound by heating it
What are all the carbonates and oxides produced?
All white solids
What does thermal stability do down the group?
Thermal stability increases
Why does thermal stability decrease down the group?
More heat is needed to break it down and the more reactive the metal, the more stable it is
Show the thermal decomposition of calcium carbonate
CaCO₃(s) → CaO(s) + CO₂
What is the test for the thermal decomposition of calcium carbonate?
1) Heating and bubbling gas through limewater turns it milky 2) add acid and bubble gas through limewater
How would you test for calcium sulphate?
Add BaCl2 forms white ppt
How do you test for calcium hydroxide?
pH paper shows its alkali
