O.
What happens when a small amount of solid rubidium chloride is dissolved in water?
Nothing happens
, because rubidium chloride is insoluble in water. The water molecules surround each ion in the solid RbCl, separating the Rb ions from the Cl ions. The solid undergoes a chemical change by reacting with the water.
