Aqua regia can dissolve noble metal due to the formation of:
Correct answer: C. Nitrosyl chloride
- A. Nitrous acid
- B. Nitric oxide
- C. Nitrosyl chloride
- D. Nascent nitrogen
Explanation
Aqua regia is formed upon mixing of concentrated hydrochloric acid and concentrated nitric acid, chemical reactions occur. These reactions result in the volatile products nitrosyl chloride and chlorine gas:HNO3 (aq) + 3 HCl (aq) → NOCl (g) + Cl2 (g) + 2 H2O (l)NOCl formed is actually that which can dissolve these noble metals.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
