Solid lithium oxide, the basic anhydride of lithium hydroxide reacts with water to make lithium ions and hydroxide ions.
Li2O(s) + H2O(l) --> 2LiOH(aq) ...... molecular equation
Li2O(s) + H2O(l) --> 2Li+ + 2OH- ..... ionic equation, and net ionic equation
BUT!!!!! The decomposition of potassium chlorate into KCl and O2 gas does not take place in aqueous solution. The equation should be.
2KClO3(s) --> 2KCl(s) + 3O2(g)
No ionic equation. There is nothing in solution.
This reaction does not occur in aqueous solution.
2Na(s) + I2(g) --> 2NaI(s)
No ionic equation. There is nothing in solution.
Clearly, to have an ionic equation there must be ions, and to have ions the salts have to be dissolved in water.
