\(\mathrm{Pt}+3: 1\) mixture of (conc. \(\mathrm{HCl}+\) conc. \(\mathrm{HNO}_3\) ) \(\rightarrow[\mathrm{X}]^2\) What is the oxidation state of Pt in \([\mathrm{X}]^{2-}\) complex ion?
- A 2
- B 3
- C 4
- D 6
Answer & Solution
Correct Answer
(C) 4
Step-by-step Solution
Detailed explanation
When Pt reacts with a \(3: 1\) mixture of concentrated hydrochloric acid \((\mathrm{HCl})\) and concentrated nitric acid \(\left(\mathrm{HNO}_3\right)\), It forms a solution known as aqua regia. aqua regia is capable of dissolving platinum by forming chlorocomplexes. The…
