sodium carbonate = sodium ions + carbonate ions.
In solution, some of the carbonate ions mop up protons from the water to form hydrogencarbonate (bicarbonate) ions. The protons came from water molecules, so there is a corresponding hydroxide ion left over for each bicarbonate ion.
sodium carbonate + water = sodium ions + carbonate ions + hydroxide ions + bicarbonate ions.
Write out a balanced equation as an exercise if you like, concombres.
“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli
