Q. The formula of tetraammineaquachloridocobalt(III) chloride is
A) [Co(NH₃)₄(H₂O)Cl]Cl₂
B) [Co(NH₃)₄Cl₂]·H₂O
C) [Co(NH₃)₄]Cl₃·H₂O
D) [Co(NH₃)₄(H₂O)Cl]Cl
Explanation
[Solution from source] The coordination sphere holds four NH₃, one H₂O and one Cl⁻ around Co³⁺, giving charge +3 − 1 = +2, so two chloride counter-ions are needed: [Co(NH₃)₄(H₂O)Cl]Cl₂. Answer (1).
