Why LiHCO3 does not exist in form of solid ??
Dear Student,
@vaibhav !Good to see that you tried to answer. But, I would like say that the correct answer to this question is..
LiHCO3 is found in solution form while rest alkali metals hydrogen carbonates are solid due to the anomalous properties of Li and it's diagonal relationship with the Mg.
Following are the points of difference between Li and other alkali metals.
(i) it's exceptionally small size.
(ii)it's high polarizing power(charge/radius ratio).
@WannaChat! Hope this answers your query.
Good Luck!
