Short Answer TypeWrite two properties of lithium carbonate in which it differs from other alkali metal carbonates.
Why is LiF almost insoluble in water whereas LiCl in soluble not only in water but also in acetone?
How would you explain that the following observations?
LiI is more soluble than KI in ethanol?
As the size of Li+ ion is much smaller than K+ ion, therefore Li+ ion can polarise bigger I- ions to a greater extent than K+ ions (Fajan rule). As a result, LiI is more covalent than KI and hence is more soluble in ethanol. (organic solvent).
