existence

eure:
SnCl₂ is in +2 oxdn state (Sn)

while in Sn₂CO₃ it is in +1

while no oxdn redn reaction is occuring..

this i wrote on the basis of the reaction that uve given. im not sure

ya,eure,asish is right. Factually, in the p-block groups ( Sn belongs to Gr-14 ), the difference in the oxidation
states of the elements present is always 2. i mean Sn can exist in 0 , +2 and +4 oxidation states only, not
in any of the intermediate ones. this happens due to inert pair effect , which disables the inner s-electrons
to participate in bonding. this creates a difference of 2 in oxidation states as a pair of electrons don't participate in bonding

thus Sn₂CO₃ doesn't exist as here Sn exhibits +1 oxidation state.

but SnCO₃ does exist and the reaction : SnCl₂ + Na₂CO₃ → SnCO₃ + NaCl is very possible and is a double displacement reaction.

yeah I know that +! state doesnt exist...dont know why I write that in ques..but my original ques was that
why this reaction doesnt take place ??
SnCl2 + Na2CO3 → SnCO3 + NaCl

becoz in book its given
SnCl2 + Na2CO3 →SnO+CO2+NaCl

can anyone compare the reactions ????thermodynamically ??

Okkk....thanx.....
infact BIG THANK YOU [4]
