a) Hoàn thành sơ đồ chuyển hóa Sơ đồ này mô tả quá trình từ muối đồng (II) sunfat tan trong nước tạo phức aqua, sau đó phản ứng với kiềm và amoniac. Các phương trình phản ứng như sau:
(1) Hòa tan CuSO_4 vào nước:
CuSO4 + 6H2O -->[Cu(H_2O)_6]SO4
Phản ứng tạo phức bát diện hexaaquacopper(II))
(2) Tác dụng với dung dịch kiềm (như NaOH hoặc NH_3 loãng):
[Cu(H2O)6]SO4 + 2NaOH --->[Cu(OH)_2(H_2O)_4] + Na_2SO_4 + 2H_2O
(Tạo kết tủa xanh lam đồng(II) hydroxide dạng phức trung hòa)
(3) Tác dụng với dung dịch NH_3 dư:
[Cu(OH)2(H2O)4] + 4NH3 --->[Cu(NH3)4(H2O)2](OH)2 + 2H2O
(Kết tủa tan tạo thành dung dịch màu xanh lam thẫm đặc trưng của phức chất ammine)
b) Phức chất nào có dạng bát diện? Trong hóa học vô cơ lớp 12, các phức chất của Cu^{2+} với số phối trí là 6 thường có dạng hình học là bát diện (octahedral). Dựa vào sơ đồ, cả 3 phức chất trên đều có dạng bát diện vì chúng đều có tổng số phối tử xung quanh nguyên tử trung tâm Cu là 6: [Cu(H_2O)_6]^{2+}: Có 6 phối tử H_2O. [Cu(OH)_2(H_2O)_4]: Có 2 phối tử OH^- và 4 phối tử H_2O (tổng là 6). [Cu(NH_3)_4(H_2O)_2]^{2+}: Có 4 phối tử NH_3 và 2 phối tử H_2O (tổng là 6).
