The compound which purely acidic character is:
- A
Mg (OH)2
- B
AI(OH)3
- C
Si (OH)4
- D
None of the above
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.
Si(OH)4 is a pure acid because it can donate a proton to form H+ ions in water, while Mg(OH)2 and Al(OH)3 are basic in nature as they can accept a proton to form OH- ions in water.
