Question

Give a short account of heating effect on metal carbonates based on the activity series ?

Answer 1

The metals placed higher in the activity series (i.e. Na and K) are stable to heat and soluble in
water.
Whereas metals like Ca, Mg, Al, Zn, Fe, Pb, Cu decompose on heating with decreasing vigour to
form metal oxide and carbon dioxide.
The metals which lie below in the activity series (i.e. Hg, Ag) decompose on heating to form
metal, oxygen and carbon dioxide.
