Question

The correct statements among the following are:

I. Due to greater polarizing power of $L{i}^{+}$, $L{i}_{2}C{O}_3$ is most stable
II. $LiHC{O}_3$ does not exist as solid
III. $NaN{O}_3$ on strong heating gives $NaN{O}_2$ whereas $LiN{O}_3$ will give $L{i}_{2}O$
IV. Sodium & Potassium ions are involved in the transport of sugars and amino acids into the cells
V. $LiF$ is less soluble due to smaller hydration energy of $L{i}^{+}$ ion

• A. I, II & V
• B. III, IV & V
• C. II, III & IV
• D. I, III & V

Answer 1

The correct option is C

II, III & IV

$L{i}_{2}C{O}_3$ is unstable and $L{i}^{+}$ has high hydration energy.
