Question

which doesnot exist in solid state? 1.LiHCO3 ,2.Ca(HCO3)2 ,3.Zn(HCO3) ,4.AgHCO3 (a) 1,2,3,4 (b)1,2,3 (c)1,2,4 (d)2,3,4

Answer 1

Answer:

1,2,3,4

Explanation:

The metal bicarbonates (i)LiHCO3 (ii)Ca(HCO 3 )2 (iii)Zn(HCO3 ) 2 (vi) AgHCO3  does not exist in solid state. However the metal bicarbonate  NaHCO3  exist in solid state.  The alkali metals are highly electropositive, these are the only elements which form stable solid bicarbonates. However lithium due to its less electropositive nature, does not form solid bicarbonate.
