he ratio of [HA]/[A-] will stay constant as both concentrations of salt and acid
would be diluted by the same proportion.

Bronsted-Lowry acid a proton donor.
Bronsted-Lowry base proton acceptor
What is H3O+? hydronium ion
definition of pH -log10[H+]
How do you get [H+] from 10^(-pH)
ph?
the ionic product of water [OH-][H+]
Is dissociation an endo or endothermic
exothermic reaction?
Why is the concentration of The concentration of water is so large and constant the
water not included in equilibrium equation can be simplified
Kw?
How does temperature affect The hotter the water is, the more dissociated it is and the
Kw? larger its Kw value.
What is the value of Kw at 10^(-14)
room temperature?
what is a weak acid? An acid that partially dissociates in solution
What is a strong acid? an acid that fully dissociates in solution
What is Ka? ([H+][A-])/[HA]
What does a large Ka value The larger ka the stronger the acid.
mean?
Ka= 10^-pKa
Definition of pKa -log10Ka
[H+] is always equal to [A-]
When you dissolve a weak
monoprotic acid in solution Ka= [H+]^2/[HA]
what happens?
