Question

Which of the following statements best describes what happens when a small amount of solid rubidium chloride is dissolved in water?

Question 4 options:

The solid RbCl breaks apart into separate Rb and Cl atoms by interacting with the water molecules.

The heat from the warm water melts the solid, making it a liquid.

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.

rubidium chloride is an ionic compound when it dissolves in water

i.e solubilty of ionic compound is more in water because water is polar molecule

then the water molecules surround each ion in the solid Rbcl , separating the Rb ions from the cl ions

so answer is option 4
