Question

Write the names of counter ions in
a) Hg[Co(SCN)4] and b) [Pt(NH3)4]Cl2​

Answer 1

Hey Dear,

◆ Counter ions -

Ions which stabilize the charged complexes are called as counter ions.

# In given examples -

a) Hg[Co(SCN)4] -

Here, actual co-ordination complex is [Co(SCN)4)]-. This extra negative charge is balanced by adding counter-ion Hg+.

b) [Pt(NH3)4]Cl2 -

Here, actual co-ordination complex is [Pt(NH3)4]++ . This extra positive charge is balanced by adding counter-ion Cl-.

Thanks dear...
