When inorganic acids, bases or salts dissolve in water, they dissociate. What does this mean?
|
dissociate - they separate into ions and become surrounded by water molecules
|
|
|
acid
|
a substance that dissociates into one or more hydrogen ions (H+) and one or more anions (negatively charged ion)
|
|
|
What is another name for an acid?
|
proton donor because H+ is a single proton with one positive charge
|
|
|
base
|
removes H+ from a solution and is a proton acceptor
|
|
|
salt
|
when dissolved in water, dissociates into cations and anions, neither of which is H+ or OH+
|
|
|
True or False.
Acids and bases react with one another to form salts. |
True. EX: HCl + KOH -> H+ + Cl- + K+ + OH- -> KCl + H2O
Acid + Base -> Dissociated ions -> salt and water |
|
|
What is the pH scale?
|
a way to express a solution's acidity or alkalinity; scale extends from 0 to 14
|
|
|
pH 0 is _______________; pH 7 is _______________; pH 14 is _______________.
|
pH 0 = acidic
pH 7 = neutral pH 14 = basic (alkaline) |
|
|
What does a pH scale of 7 mean?
|
midpint of pH scale where the concentration of H+ and OH- are equal
|
|
|
Homeostatic mechanisms maintain the pH of blood between __________ and __________.
|
7.35 and 7.45
|
|
|
buffer system
|
function to convert strong acids or bases into weak acids or bases.
|
|
|
buffers
|
the chemical compounds that can convert strong acids or bases into weak ones
|
|
|
carbonic acid-bicarbonate buffer system
|
can compensate for either an excess or a shortage of H+
