metal oxides are known as basic oxides only non metalic base is ammonium hydroxide . group ii oxides are generally insoluble
an alkali
Potassium oxide reacts with water to form soluble potassium hydroxide.
Rubidium oxide react with water.
Of course it is!
Yes.
an alkali
Potassium oxide reacts with water to form soluble potassium hydroxide.
Sort of. Sodium oxide reacts with water to form sodium hydroxide, which is soluble.
An alkaline earth is an oxide of the elements of group II of the periodic table - not as basic as the alkalis and not so soluble in water.
Rubidium oxide react with water.
The salt of calcium oxide is calcium hydroxide which is a strongly basic salt, though it is hardly soluble ( Ca(OH)2 ).
In water, no.
Of course it is!
Yes.
HgO-Is Mercury oxide
Iron oxide is only soluble when placed in concentrated mineral acids. It is insoluble in organic and water based solvents.
Yes, Calcium oxide is an alkaline as when Calcium oxide reacts with water (H2O) it dissolves as it is a soluble metal oxide. The solution produced when this occurs is an alkaline solution. This proves that Calcium oxide is an alkaline
