acids and bases Flashcards
the shape of a water molecule is a
tetrahedron
a molcule (like h20) with a charge seperation is called a
polar molecule
electrons shared equally are called a
nonpolar molecule
water has a ________
high specific heat
water is a ______
universal solventa
a solution is a
mixture of two or
more substances that
is uniform at the
molecular level.
a solutoin of 2 or more solids is called a
alloy
in a ____ mixture the particles can range widely in
size.
suspension
___________ are mixtures, and look like
solutions, but their particles are
too small to settle to the bottom of
their container over time.
colloids (ex mayo)
_____ occurs when you shine a light through a substance
tyndall effect
____ has the greater amount
solvent
a solution is _______ if it contains as much
solute as the solvent
can dissolve.
saturated
how to find concentration
C= amount of solute/amount of solution
other ways of expressing concentration are
molarity and mass percent
______ is equal to the moles of
solute per liter of solution.
molarity
equation to find molarity
m= moles of solution/ liter of solution
how to find mass percent
the mass of the solute
divided by the total mass of the
solution multiplied by 100%.
When the rate of dissolving equals the
rate of coming out of solution
equlibirum
a ______is a compound that dissolves in
water to make a particular kind of solution.
acid
A ____ is any substance that
dissolves in water and produces
hydroxide ions
base
how to find ph
ph= -(-exponent)
