Would you expect metal oxides to be acidic or basic? and why?

Answer 1

Basic.

But the reason is quite different. When the metal oxides are solvated, they dissociate into the metal ion as cation and oxide ion as the anion. The metal ions are designed to be cations. They are quite stabilised when they are solvated, reaching the noble gas configuration by completing their octets.

The oxide ions on the other hand are stable, but due to their extremely large charge/mass ratio attract a lot of water molecules to themselves. So they undergo solvolysis and thus are converted to the more stable hydroxide ions in solution. This causes a rise in pH of the solution and make s the solution basic.

Answer 2

metal oxides are basic in character. when they come in contact with water, they produce a base or metal hydroxide. one way to test if it forms a base is to add litmus paper. if it changes blue after you add the metal oxide to the water, then it is a basic oxide.

Answer 3

Metal oxides are basic, by definition!

Metals accept electrons, so their oxides are basic.

Or aqueous solutions (dissolved in water) of metallic oxides turn red litmus paper blue! So, they are basic

Answer 4

metal oxides are expected to be basic oxides because they react with acids to form salt and water

Answer 5

Metal oxides are basic .

Then they react , you have ( bivalent metal example) a scheme like this

Me O + H2O ---> Me(OH)2

Answer 6

Basic. They react with water to produce metallic hydroxides. (generally).
