soluble and insoluble substances Flashcards
define soluble
Soluble substances are those that dissolve, for example sodium chloride (table salt).
define insoluble
Insoluble substances do not dissolve, for example calcium carbonate (chalk).
when are solutions formed
Solutions form when the particles of the solute disperse through the solvent.
what is a solvent
The solvent is the substance that can dissolve other substances, such as water.
what is a solute
The solute is the substance that has been dissolved.
what are some properties of solutions
Solutions have uniform properties, for example they are always transparent and allow light to pass through.
Some solutions may be coloured.
what is dissociation
When an ionic solid dissolves, it breaks down into its component ions. This is called dissociation.
how does dissociation occur
dissociation occurs when the solvent molecules surround the ions in the lattice and break it apart
what does (aq) stand for and when is it used
When ions are dissolved in a solution, the subscript (aq), for aqueous is used.
what does (aq) mean
it means that the ions are dissolved in water.
