conduct electric current
aqueous solutions of bases
Amino Acids
small compounds in your body

What is a normal pH?
7.35 -7.45
Amphiprotic
Can act as both acids and bases
Buffer
Will neutralize either acids or bases to some degree.
weak acid
an acid that ionizes only slightly
Standard Solution
Knowing the concentration of a solution exactly
Strong Bases dissociate ...% to form OH-
100
According to Lewis, a substance can accept or donate a pair of electrons to form a ____ bond
covalent
solubility
the ability of one substance to dissolve in another at a given temperature and pressure
Carboxylic Acids
organic acids that include carbon. WEAK. Acetic acid- vinegar.
arrhenius acid
Produces H+ ions when dissolved in water
titration
a measured amount of a solution of unknown concentration is added to a known volume of a second solution until the reaction between them is just complete
oxyacid
an acid that is a compound of hydrogen, oxygen, and a 3rd element (usually a nonmetal)
lewis model
an acid is an electron-pair acceptor and a base is an electron-pair donor
indicator
a chemical that changes color based on pH
pH indicators
used to determine pH of a solution
salt
ionic compound made up of a cation from a base and an anion from an acid
what do acids form when they react with metals?
Hydrogen Ions
self-ionization of water
2 water molecules produce a hydronium ion and a OH- by a transfer of a proton
STRONG PROTOLYTE
a substance that has a great tendency to accept or donate a proton.
lewis acid
an atom, ion, or molecule that accepts a pair of electrons
The conjugate base of the acid HCl (what ion?)
Chloride ion
bronsted lowry theory base
a substance that accepts a proton
base ionization constant
the value of the equilibrium constant expression for the ionization of a base
what turns pink when there is a base present?
Phenolphthalein
equivalence point for strong acid and strong base titration
pH = 7 (neutral)
conjugate base
the base formed when an acid donates a proton
hydrogen ion
an atom of hydrogen that has lost its electron
How are acids classified as?
They are classified as monoprotic, diprotic, or triprotic depending on the number of protons each may give up; examples are HCL, H2CO3, and H3PO4
salt dissociation:
cation (+)
(1) doesn't react with H2O [G1 & G2 cations]
(2) stronger acid then water [NH4+, Be2+, Cu2+, Zn2+, Al3+, Cr3+, Fe3+]
What does pOH measure?
Concentration of the OH- ions in a soluton
A base (B) gains a proton to form the
conjugate acid ( HB+]
what are the causes of an increased anion gap?
mud piles; methanol, uremia, DKA, paraldehyde, intoxicants, lactate, ethylene glycol, salicates.
Why do you use insulin and dextrose for Hyper K?
Promotes the uptake of K into the cells. K follows the insulin/dextrose.
