The oxide ion in CaO (O2-) is a very strong base, meaning it will easily take a hydrogen ion (H+) from a molecule. In water the oxide ion take a hydrogen ion from a water molecule, forming to hydroxide ions.
O2- + H2O --> 2OH-
In this reaction the oxide ion acts as a base and the water molecule as an acid, at least by the Bronsted-Lowry definition.
The reaction is Ca + H2O ---> Ca(OH)2 .
Calcium is a metal and metals generally mix with water (H2O) to form basic hydroxides. Thus, a reaction involving Calcium and Oxygen results in the formation of Calcium Hydroxide.
1. Calcium hydroxide is a polar compound.
2. The solubilty of calcium hydroxide in water is not important.
CO2+Ca(OH)2= CaCO3+ H2O
CaO(s) + H2O(l) -> Ca(OH)2 (aq)
- Sand does not dissolve in water- Plastic does not dissolve in water- metals do not dissolve in water
A substance is 'insoluble in water' if it will not dissolve in water, although it may dissolve in another solvent.
No glue that I know of can dissolve chalk.
Salt and Sugar dissolve in water.
No. Oil will dissolve in fatty (hydrophobic) liquids, not in hydrophilics like water.
The solubility in water of calcium hydroxide: 1,73 g/L at 20 0C.
In one mole of this solution, there are seven moles of H2O.

Yes, It Does Dissolve in water.
No, but salt does dissolve in water.
No. Lipids do not dissolve in water.
mixture dissolve in a water
Yes it does dissolve in tap water. It can really dissolve in any water.
Nope... it is not.
Calcium Hydroxide, or CaOH2, is a base. Generally compounds containing hydroxyl groups and metals will act as bases in reaction.
Nutilite's vitamins dissolve in water.
No. Ionic bonds dissolve in water the best.
