Identify from following the conjugate base of [ Zn ( H ₂ O )₄]²⁺

Options

A[ Zn ( H ₂ O )₄]²⁻ , NH ₃
B[ Zn ( H ₂ O )₃]²⁻
C[ Zn ( H ₂ O )₃ OH ]⁺
D[ Zn ( H ₂ O ) H ]³⁺

Correct answer

C. [ Zn ( H ₂ O )₃ OH ]⁺

Step-by-step solution

According to the Bronsted-Lowry theory, a conjugate base is formed when an acid loses a proton ( H ⁺ ). The given species is [ Zn ( H ₂ O )₄]²⁺ . Removing a proton ( H ⁺ ) from one of the coordinated water molecules gives: [ Zn ( H ₂ O )₄]²⁺ [ Zn ( H ₂ O )₃( OH )]⁺ + H ⁺ Thus, the conjugate base is [ Zn ( H ₂ O )₃ OH ]⁺ . Answer: [ Zn ( H ₂ O )₃ OH ]⁺
