On treatment with cold water, an element (A) reacts readily liberating a colourless, odourless gas (B) and a solution (C). Lithium is reacted with (B) yeildng a solid product (D) which effervesce with water to give a strongely basic solution (E). When `CO_(2)` gas is bubbled through solution (C), a white ppt. (F) is formed but this redissolved forming solution (G) when more `CO_(2)` is passed. Precipitate (F) effervesced when moistened with conc. HCl and give deep red colouration to Bunsen burner flame. (F) on heating with excess of carbon at `2000^(@)`C give (H).
