Unit 3 - Acid/base Flashcards
1
Q
Ph scale
A
Acid<6
Neutral=7
Base>8
2
Q
Arrhenius theory
A
Acids release H+ ions
Bases release OH- ions
Arrhenius Acid + Arrhenius base=salt and water
e.g. HCl + NaOH -> NaCl + H2O
3
Q
Bronstead-lowry acids and bases
A
BL Acid donates H+ ion (proton)
BL Base accepts H+ ions
e.g. HCL + H2O -> H3O^+ + Cl-
4
Q
water ion product expression
A
Kw=[H3O] [OH]
Kw is the ionization constant for water
5
Q
pH/pOH/H3O/OH calculations
A
pH= -log(H3O) pOH= -log(OH) H3O= 10^-pH OH= 10^-pOH
6
Q
% ionization calculation
A
%ionization= [H+]eq/[HA]initial x 100
7
Q
Titrations
A
MaVa = MbVb
