Which of the following statements best describes what happens when a small amount of solid rubidium chloride is dissolved in water?
A)The heat from the warm water melts the solid,making it a liquid.
B)Nothing happens,because rubidium chloride is insoluble in water.
C)The solid RbCl breaks apart into separate Rb and Cl atoms by interacting with the water molecules.
D)The water molecules surround each ion in the solid RbCl,separating the Rb ions from the Cl ions.
E)The solid undergoes a chemical change by reacting with the water.

Question

Quizplus · Accepted Answer

When a small amount of solid rubidium chloride is dissolved in water, the water molecules surround each ion in the solid, separating the Rb ions from the Cl ions. This is because water is a polar solvent and can form hydration shells around the ions, stabilizing them in solution. Rubidium chloride is a soluble ionic compound and therefore can dissociate in water to form free ions. No chemical reaction takes place in this process.
