DESCRIPTION
Solute A substance that is dissolved, such as saltTRANSCRIPT
Solution Chemistry
Solutions• Homogeneous mixtures of
substances composed of at least one solute and one solvent
Solute• A substance that is dissolved,
such as salt
Solvent• The medium in which a
solute is dissolved, such as water
Electrolytes• Aqueous solutions that
conduct electricity
Nonelectrolytes• Aqueous solutions that do
not conduct electricity
Dissociation• The separation of ions that
occurs when an ionic compound dissolves in water
Ionization• the process by which a
neutral atom or molecule is converted to an ion
Pure Substance• Consists of only 1 particular
kind of matter and therefore always has the same composition and properties throughout
• Pure substances are classified into ELEMENTS (i.e. Fe, O2) or COMPOUNDS (i.e. H2O, CO2)
Mixture• A combination of 2 or more
pure substances, each of which retains its own chemical and physical properties
Heterogeneous mixture
• a non-uniform mixture consisting of more than 1 phase (portion)
Homogeneous Mixture
• A solution• uniform throughout, cannot
see the different parts of the mixture
Liquid Solutions• Made by dissolving solids,
liquids or gases in liquids• i.e. sugar in water, methanol
in water, carbon dioxide in water
Gaseous Solution• Made by dissolving solids,
liquids or gases into gas. • All gases mix in all
proportions to produce solutions
Solid Solution• Made by mixing solids,
liquids or gases with a solid substance• i.e. alloy metals (brass is zinc
dissolved in copper)
