The compound which purely acidic character is:
Correct answer: C. Si (OH)4
- A. Mg (OH)2
- B. AI(OH)3
- C. Si (OH)4
- D. None of the above
Explanation
The compound where hydrogen is attached to the highly electronegative element is considered to be most acidic. Si(OH)4 is considered most acidic because Silicon is too similar in electronegativity to oxygen to form ionic bonds. Therefore, because silicon dioxide does not contain oxide ions, it has no basic properties and more acidic properties therefore It will react with strong bases to form silicate salts.
