POST QUESTIONS AND SOLUTIONS VERIFIED
◉ dissolution. Answer: the process of dissociating a solute into
smaller particles by a solvent to produce a solution
◉ effervescence. Answer: the rapid release of a dissolved gas from a
liquid
◉ electrolyte. Answer: any substance that ionizes when dissolved or
melted to become an electrical conductor
◉ enthalpy of solution. Answer: the net energy change when a solute
is dissolved in a solution
◉ immiscible. Answer: referring to liquids that are completely
insoluble in each other
◉ ionize. Answer: to break up a substance into individual cations
and anions; to become an ion by gaining or losing electrons
,◉ miscible. Answer: referring to liquids that are soluble in each
other in any proportion
◉ nonelectrolyte. Answer: any substance that does not ionize when
dissolved
◉ polarity. Answer: the degree of contrast between two opposing
forces
◉ recrystallization. Answer: the formation of crystals by particles of
a solute that had previously dissolved from a crystal
◉ saturated solution. Answer: a solution that contains the maximum
amount of solute that will dissolve at a particular temperature and
pressure; a solution that has reached solution equilibrium
◉ solution equilibrium. Answer: the state in which the processes of
dissolution and recrystallization of a solute occur at the same rate
◉ solvation. Answer: the process whereby particles of a solvent
completely surround the particles of a solute and hold them in
solution
,◉ supersaturated solution. Answer: a solution that contains more
solute than what would normally dissolve at a particular
temperature and pressure
◉ unsaturated solution. Answer: a solution that contains less solute
than a saturated solution
◉ 1) Reviewing the three types of mixtures, solutions, colloids, and
suspensions, you can say that a solution is different from the others
in that:. Answer: a solution is homogeneous and has particles that
are less than 1 nm in diameter
◉ 2) Any substance that ionizes when it dissolves or melts to
become an electrical conductor is called a(n) __________.. Answer:
electrolyte
◉ 3) Any substance that does not ionize when dissolved or melted is
called a(n) __________.. Answer: nonelectrolyte
◉ 4) _______ is the process of dissociating a solute into smaller
particles by a solvent to produce a solution.. Answer: Dissolution
◉ 5) _______ is the process whereby particles of a solvent completely
surround the particles of a solute, and disperse them throughout the
solvent particles, which holds them in solution.. Answer: Solvation
, ◉ 6) ________ is to break a substance into cations and anions..
Answer: Ionization
◉ 7) Solubility is determined by the molecular or ionic structures of
the solute and the solvent, and by the _______ that hold together the
particles of each substance.. Answer: intermolecular forces
◉ 8) What happens if the solvent-solute attraction is greater than
the solute-solute attraction when two substances are mixed?.
Answer: The solute particles are pulled apart and dispersed
throughout the particles of the solvent, which holds the particles of
the solute in solution.
◉ 9) During the process of _______ the solute maybe completely
ionized, partially ionized, or it may remain intact.. Answer:
dissolution
◉ 10) Many ionic compounds are _______ because they completely
ionize in water to create a solution with charged ions that can act as
an electrical conductor.. Answer: strong electrolytes
◉ 11) Some ionic compounds are _______ because they partially
ionize in solution.. Answer: weak electrolytes
