1. Which of the following base ionizes in aqueous solution to produce three hydroxyl ions per molecule ?
2. ‘A’ burns in oxygen to form ‘B’ with lilac flame, ‘B’ dissolves in water to form ‘C’. ‘C’ reacts with an acid commonly called aquafortis to form ‘D’ and ‘E’. ‘D’ on heating decomposes to ‘F’ and \(O_2\). ‘D’ is an ionic compound which dissociates forming a positive ion other than hydrogen ion and negative ion other than hydroxyl ion. If ‘E’ changes anhydrous \(CuSO_4\) to blue.
Identify A, B, C, D, F and their nature respectively.
