Question

Complete the given reactions:
$+Water\to Acid$
$+Water\to Base$

• A. Neutral oxide
• B. Non-metallic oxide
• C. Metallic oxide
• D. Salt

Answer 1

Answer: (B), (C)

The correct options are
B Non-metallic oxide
C Metallic oxide

Non-metallic oxides, or acidic oxides, on reacting with water form acids.
Example:
$C{O}_2\left(g\right)+H_{2}O\left(l\right)\to H_{2}C{O}_3\left(aq\right)$
Metallic oxides, or basic oxides, on reacting with water form bases.
Example:
$CaO\left(s\right)+H_{2}O\left(l\right)\to Ca\left(OH{)}_2\right(aq)$
