what is a bronsed lowery acid
proton doners, (donate protones to a base)
What are bronsted lower bases
proton acceptors ( accept proton from acids)
what is special about water
it can accept of donate a proton (h+) and is therefor referred to as amphiprotic
for neutral solutions, what is the OH/H3O concentration equal to
1 x 10 ^-7
how do you calculate pH
pH= -log[H3O]
how do you calculate pOH
pOH=-log[OH]
what is kw equal to for solutions at 25 degrees
1 x 10 ^ -14
what is the definition of strong acids
strong acids ionize completely in water
what are examples of strong acids
HClO4, H2SO4, HNO3, HBr, HI
what is the definition of a strong base
disassociation reaction happens completely in water
what are examples of strong bases
LiOH, KOH, Ca(OH)2, Sr(OH)2, Ba(OH)2
what is the definition of a weak acid
partially ionize in aqueous solution and establish an equilibrium (forms an equilibrium)
what is the definition of a weak base
a weak base is one that does not completely disassociate in water ( forms an equilibrium)
how do you calculate % ionization for acids
[H3O]/[HA] x 100
how do you calculate % ionization for bases
[OH]/[BOH] x 100
what is % ionization for strong acids or bases
100%
what is the conjugate base of a weak acid
a weak base
what is a buffer
a buffer is a solution which presents small pH changes when concentrated strong acids or bases are added to it, hs similar concentrations or a weak acid and salt of its conjugate base or similar concentration of a weak base and a slat of its conjugate acid
what happens as the concentration of CO2 in the atmosphere increases
the concentration of aqueous CO2 in natural waters increases (pH decreases)
