Formation of Oxides when Non-metal and Metal React with Water
Non-metal oxides and metal oxides are formed when non-metals and metals react with water respectively. Let's look at some examples and explanations for both cases:

Non-metal Reacts with Water:
- When a non-metal reacts with water, it forms an acidic oxide.
- For example, when sulfur dioxide (SO2) reacts with water, it forms sulfuric acid (H2SO4).
- The reaction can be represented as:
SO2 + H2O → H2SO4

Metal Reacts with Water:
- When a metal reacts with water, it forms a basic oxide.
- For example, when sodium (Na) reacts with water, it forms sodium hydroxide (NaOH) and hydrogen gas (H2).
- The reaction can be represented as:
2Na + 2H2O → 2NaOH + H2
In the case of non-metals, the oxides formed are acidic because they react with water to produce an acid. On the other hand, when metals react with water, they form basic oxides which react with water to produce a base. This difference in reactivity is due to the nature of the elements involved and their ability to gain or lose electrons.
