What are metal oxides with examples?
Metal oxides are oxides of metal. They are ionic in nature and form basic oxides. Eg: Na2O, MgO,etc
Are metal oxides neutral?
Many metal oxides are alkaline and form hydroxides in the presence of water.
Is metal oxide is a base?
Yes, certain metal oxides, mostly from the middle groups of the transition metals are acidic. Chromium and rhenium, for example, both form oxides which are acidic in water.
Metals tend to form?
Metal oxides which are bases
Which type of oxide is formed when metals combine with oxygen?
Metal oxides form alkalis when they dissolve in water. Non-metal oxides for acids. For example: carbon dioxide + water --> carbonic acid magnesium oxide + water --> magnesium hydroxide
When metal are burned in air they form metal oxide?
Burning is an oxidation; oxides are then formed.
Will na2o react with water to form a acidic solution?
No, it will form a basic solution of Sodium Hydroxide as per the following equation. Na2O + H2O ---> 2NaOH As the solution will have OH- ions so it will be basic. Na2O is a basic oxide and basic oxide dissolve in water to form bases( here NaOH). Acidic oxides dissolves in water to form acids. Alkali metal(group 1 of periodic table) oxides are always basic oxides, but all metal oxides may not be basic( some transition metal oxides are acidic).
What is a O2?
O2- is an oxide ion which reacts with metal to form oxides of the metal. For example: MgO, Na2O
What is the result when most nonmetallic oxides react with water?
Non metal oxides tend to react with water to form acidic solutions.
Are metal's oxides gases or bases?
Metal oxides are typically basic.
What do metal oxides form when dissolved?
They form bases.....for eg CaO+H2O---->Ca(OH)2
What happens if metals react with water?
In the case of rust anyway, metal oxides form
