What causes a base to dissociate?
The polar water molecules pull on the ions of the base.
How many molecules does alcl3 dissociate into?
It does NOT form molecules. When AlCl3 'breakdown ' it form the IONS Al^(3+) & 3 Cl^(-) AlCl3(s) IS a molecule.
What are the particles in distilled water?
Distilled water only has H2O molecules. A very small number of these molecules dissociate to form H+ and OH- ions.
What are molecules that dissociate in water releasing hydrogen ions?
HCl (hydrochloric acid)
What happens when you mix water with hydrochloric acid?
HCl is soluble in water. It is a strong acid and will dissociate completely to form H+ ions and Cl- ions.
What is salt water a mixture or solution?
A solution. The salt molecules dissociate into ions in the water.
What causes a base to dissociate?

What cause an acid or base to dissociate?
The polar water molecules pull apart the ions of the acid or base
What happends when sodium chloride dessolves in water?
The sodium and chloride ions dissociate in a process called solvation, in which water molecules surround the individual sodium and chloride ions.
Why do ionic compounds behave somewhat like polar molecules in a solution?
Because they dissociate into charged ions. Because they dissociate into charged ions.
Why do acids or bases dissociate?
polar water molecules pull apart the acid or base by pulling on the charged ions.
What are molecules that dissociate in water releasing hydrogen ions?
HCl (hydrochloric acid)
What happens when you mix water with hydrochloric acid?
HCl is soluble in water. It is a strong acid and will dissociate completely to form H+ ions and Cl- ions.
Is distilled water a good conductor or a poor conductor?
Distilled water is a poor conductor. For conduction in any liqiud it must have +ve and -ve charged ions. Water in pure state doesn't dissociate appreciably to give enough ions for electrical conduction. But when soluble ionic compounds are added to it, their ions help water molecules to dissociate and give more ions for good conduction.
When being dissolved what is happening to the particles?
Ionic compounds dissociate, meaning the ions separate in the liquid. Molecules like sugar maintain their form.
