Which of the following combination is acidic natureC
Correct answer: C. Si(OH)₄, HCl, H₃PO₄
- A. Si (OH)₄, NaOH, H₃PO₄
- B. HClO₄, H₂SO₄, Ca (OH)₂
- C. Si(OH)₄, HCl, H₃PO₄
- D. Mg (OH)₂, H₃PO₄, HClO₄
Explanation
The correct answer is Option C: Si(OH)₄, HCl, H₃PO₄. This combination contains HCl, which is a strong acid, contributing to the acidic nature of the overall combination. The other options either contain strong bases or bases, making them incorrect for acidic nature.

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.
