acid dissociation constant
Ka
[H+] greater than [OH-]
acidic solution
H3PO4
triprotic acid
contains less solute than can theoretically be dissolved
unsaturated solution
H3O+
hydronium ion
[OH-] and [H+] = 1 x 10*-7
nuetral solution
[OH-] greater than [H+]
alkaline solution
the number of moles of solute dissolved in 1L of solution
molarity
describes a substance that can act as both an acid and a base
amphoteric
two substances that are related by the loss or gain of a single hyrogen ion
conjugate acid-base pair
a solution in which the hydroxide-ion concentration is 1×10 *-5 M is
basic
in a neutral solution, the [H+] is
equal to [OH-]
the products of the self-ionization of water are
OH- and H+
which of these solutions is most basic?
[H+] = 1 x 10*-11
the formule of the hydrogen ion is often written as
H+
what is the pH of a soluion in which the [H+]= 1 x 10*-12
12.0
what is the pH of a .01M hydrochloric acid solution
2.0
if more slovent is added to a solution
the molartiy decreases
which of the following pairs consist of a weak acid and a strong base?
ethanoic acid, sodium hydroxide
in the reaction NH4+ + H20 == blah blah blah water is acting as a
bronsted- lowry base
a soluiton with a pH of 4
has a hydroxide-ion concentration of 1 x 10*-9M
which of hte following operation usually makes a substance dissolve faster in a solvent?
all of the above
the about of soduim cholride in 100 Ml of a 5.0M
NEVER TRUE
As an open bottle of a carbonated beverage warms, the concentration of dissolved carbon dioxide decreases
ALWAYS TRUE AT
an unsaturated solution contains less sloute than required for equillibruim
ALWAYS TRUE AT
