Plumbo−solvency refers to :
Correct answer: C. Dissolution of lead in water containing air
- A. Oxidation of lead to lead oxide
- B. Oxidation of lead to red lead
- C. Dissolution of lead in water containing air
- D. Making lead wires by forcing heated metal through a die
Explanation
Option C is correct. Plumbo-solvency refers to the dissolution of lead in water containing air. Lead is a relatively inert metal and does not dissolve readily in water. However, when lead is exposed to air, it reacts with oxygen to form lead oxide. Lead oxide is a white solid that is soluble in water. The solubility of lead oxide in water is increased by the presence of carbon dioxide. The process of dissolving lead in water containing air is called plumbo-solvency. Plumbo-solvency is used to extract lead from ores and to purify lead. Pb + O2 + H2O → Pb(OH)2

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
