What is the oxidation number of gold in the complex \([AuCl_{4}]^{1-}?\)
- A \(+4\)
- B \(+3\)
- C \(+2\)
- D \(+1\)
Answer & Solution
Correct Answer
(B) \(+3\)
Step-by-step Solution
Detailed explanation
Let assume oxidation state of
\(\text{Au}=\text{x}\)
\(\text{x}+4(-1)=-1\)
\(\text{x}-1=-1\)
\(\text{x}=-1+4\)
\(\text{x}=+3\)
\(\text{Au}=\text{x}\)
\(\text{x}+4(-1)=-1\)
\(\text{x}-1=-1\)
\(\text{x}=-1+4\)
\(\text{x}=+3\)
