उत्तर
This statement is False.
Explanation:
Oxides of metals are generally basic in nature, not acidic. When dissolved in water, metal oxides typically form bases or alkaline solutions. For example:
- Sodium oxide (Na2O) reacts with water to form sodium hydroxide (NaOH).
- Calcium oxide (CaO) reacts with water to form calcium hydroxide (Ca(OH)2).
