MCQ
Which of the following is most acidic
- A$N{a_2}O$
- B$MgO$
- ✓$A{l_2}{O_3}$
- D$CaO$
✓
Answer
Correct option: C.
$A{l_2}{O_3}$
c
$Na 2 O , MgO , CaO$ are metallic oxide of $s$ block. These maetallic oxides powerful bases, while $Al _2 O 3$ is metallic oxide of $p$ block which has comapratively more acidic character. Hence, it is the most acidic oxide among all.
