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

Question

Quizplus · Accepted Answer

When a small amount of solid rubidium bromide is dissolved in water, the polar water molecules surround each ion in the solid RbBr, separating the Rb ions from the Br ions. This process is known as hydration, and results in the formation of an aqueous solution of Rubidium and bromide ions.
