On treatment with cold wate, element (A) reacted quietly, librating colourless gas (B) and solution ( C). Lithium reacted with gas (B) and giving a solid product (D) which gave effervesence with water to give basic solution (E). When `CO_(2)` was passed thorough solution ( C), an initial whit ppt (F) was formed but this redissolved forming solution (G) when more `CO_(2)` was passed. PPT (F) effervessced when moistened to Bunsen flame. (F) on heating wiith excess of carbon at `2000^(@)C` gave (H):
