What happens to the ions if an ionic compound is dissolved?
When ionic compounds dissolve in water, they break apart into the ions that make them up through a process called dissociation. The ions dissociate and disperse in solution, each ringed by water molecules to prevent reattachment. The ionic solution turns into an electrolyte, meaning it can conduct electricity.
How do ionic compounds dissolve?
Ionic compounds dissolve in water if the energy given off when the ions interact with water molecules compensates for the energy needed to break the ionic bonds in the solid and the energy required to separate the water molecules so that the ions can be inserted into solution.
What are dissolved ions?
Ionic compounds are those composed of oppositely charged atoms, called ions, arranged in a lattice structure. If the attraction between the ions and the water molecules is great enough to break the bonds holding the ions together, the compound dissolves.
When an ionic compound dissolves in water the ions in solution can best be described as?
Note: The ionic compounds are dissolved in water then their ions are hydrated in it. The ionic compounds are water-soluble.
Why do ionic compounds dissolve?
Every ionic compound has an energy holding the lattice structure of the compound, known as lattice energy. If the hydration energy of an ionic compound exceeds its lattice energy, the lattice is broken and the ions in the compound separate, causing the compound to dissolve.
What happens to an atom when it becomes an ion?
An atom becomes an Ion (a) if it gains one or more electron(s) or (b) if it loses one or more electron(s). When it gains electrons it becomes negatively charged and is called an anion. When it loses electron(s) it becomes positively charged and is called a cation.
Do ionic compounds conduct electricity when dissolved in water?
Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.
Why are ions soluble in water?
Most ionic compounds are soluble in water. Polar water molecules have a strong attraction for charged ions and the charged ions become solvated as they dissociate into the water and ionic compounds are soluble in water.
