NH3係一隻弱鹼，佢會slightly ionize in water NH3 + H2O <=> NH4+ + OH- 之後 Fe2+ + 2OH- => Fe(OH)2
The blue precipitate is copper(II) hydroxide. The blue precipitate ... will react with the hydroxide ions to give a blue precipitateof copper(II) hydroxide. Cu^2+(aq) + 2OH^-(aq...
咦. 我所讀的化學顯示, 他們是有 precipitate 的. ions contained in ammonia solution: NH4+ and OH...)2 only. Therefore, solution cantaining Ca2+ give white precipitate with ammonia solution.
The precipitate is not yellowish-brown. Actually, the solution changes from... can even evaporate to cause the nasty smell. The colourless precipitate is C6H2Br3OH, which is only slightly soluble in water.
OH- ion is movable in aqueous solution, it will form bond with metals ions eg. A solution contains K+, Mg2+, Fe2+, Fe3+ ions, when you added NaOH drop by drop. The OH- ion will bond with Na...
