Question

Which of the following statement is false for alkali metals?

• A. lithium is strongest reducing agent
• B. all alkali metals give blue solution in liquid ammonia
• C. $L{i}^{+}$ ion is exceptionally small
• D. lithium carbonate is stable towards heat and do not decompose

Answer 1

Answer: (D)

$L{i}_{2}C{O}_3$ is the only alkali metal carbonate that decomposes to produce $C{O}_2$ .

${\text{Li}}_{\text{2}}{\text{CO}}_{\text{3}}\to {\text{Li}}_{\text{2}}\text{+}{\text{CO}}_{\text{2}}$
