Give the coordination number for each metal ion in the following compounds:
(a) [co(co3)3]3− (note that co32− is bidentate in this complex)(b) [cu(nh3)4]2+
(c) [co(nh3)4br2]2(so4)3
(d) [pt(nh3)4][ptcl4]
(e) [cr(en)3](no3)3
(f) [pd(nh3)2br2] (square planar)
(g) k3[cu(cl)5]
(h) [zn(nh3)2cl2]

a. 6(3x2=6)

B. 4(4x1=4)

C. 6(4(1)+2(1)=4+2=6

D. 4

E. 6(3(2)=6)

F. 4(2(1)+2(1)[2+2=4)

G. 5(5(1)=5)

H. 4(2(1)+2(1)=2+2=4)

Explanation:

Coordination number= no of ligands

= No of ligands X denticity

Denticity is nothing but type of ligands like mono,do and tetradentate ligands.

where is the following

explanation:

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
