acid base Flashcards
when temp is decreased
ph increase and Kw decreases
what are characteristics of acid
sour
corrosive
conducts
red
reacts with metals to form H2
characteristics of bases
bitter
corrosive
conducts
slippery
blue
acid do what H
donate
base does what with H
accepts
strong acid and weak acids do what
strong fully dissociate and weak from equilibrium
if the strong acid is on the left side of the equilibrium then
equilibrium favours products
if the strong acid is on the right side of the equilibrium then
equilibrium favours reactants
strongest acid always
react with the strongest base
the strongest acids yield the
weakest con bases
what is a ampehprotic
a compound that donates and accepts (water)
what is Kw at pure water @25 C
1.0 x 10^-14
What is Kw
Kw = H + OH
pkw
pkw = PH + poH
how to find Ph Poh
pH = -log H/OH
what’s a better conductor if two acids have two different conc
higher conc the more ions > better conductor
- Which of the following is true for all Bronsted-Lowry bases?
they accept protons
The pH of water at 85°C could be:
less than 7
the strengths of acids decrease, the strengths of their conjugate bases:
increase
conditions exists as the stoichiometric point?
moles of H* from the acid equals the moles of OH’ from the base
what is a monoprotic acid
a acid containing one ionizable hydrogen
what is a Brönsted-Lowry base
A weak Brönsted-Lowry base is a proton acceptor
what is a strong Brönsted- low stead acid
A srong Brönsted-Lowry acid is a proton donor
as temp
increases ph does what
decrease
