Flashcards in Chapter 8 Deck (27):
acids - dissolve in water to form hydrogen ions or protons
base - dissolved in water to form hydroxide ions (OH-)
defines acid as a proton (H+) donor and a base as a proton acceptor
H3O+ is referred to as the hydrated proton or...
Ammonia accepts a proton from the solvent water, producing OH-, the ...
water, owing to the fact that it possesses both acid and base properties
species formed when a base accepts a proton
species formed when an acid donates a proton
Conjugate Acid-base pair
acid and base on the opposite sides of the equation are collectively termed Conjugate Acid-base pair
self-ionization of water
Ion product for water
product of hydronium and hydroxide ion concentration in pure water
gauges the hydronium ion concentration and reflects the degree of acidity or basicity of a solution
reaction of an acid with a base to produce a salt and water
involves the addition of measured amounts of a standard solution to neutralize the second, unknown solution
one whose concentration is known with certainty
substance that changes color as the solution reaches a certain pH, is added to the unknown solution
Solution of sodium hydroxide, perhaps .10000 M, is carefully added to the unknown solution
the number of mol of hydroixide ion added is equal to the number of mol of hydronium ion present in the unknown acid
donate (as acids) or accept (as bases) more than one proton per formula unit
contains components that enable the solution to resist large changes in pH when either acids or bases are added.
measure of the ability of a solution to resist large changes in pH when a strong acid or strong base is added.
defined as a loss of electrons, loss of hydrogen atoms, or gain of oxygen atoms
is defined as a gain of electrons, gain of hydrogen atoms, or loss of oxygen atoms
Deterioration of metals caused by an oxidation-reduction
electrochemical cell that converts stored chemical energy into electrical energy
electrode at which oxidation occurs
Electrode at which reduction occurs
