The stronger the acid, the _______ the conjugate base
weaker
What are the 6 strong acids?
HCl
HBr
HI
HClO4
H2SO4
HNO3
Cations that are small and highly charged (3+) are always ___________________
Acidic
For binary acids, acidity increases to the ______ and _________ on the periodic table
E.g. HCl > HF
right, down
Which is more acidic, H2SO4 or H2SO3?
H2SO4
Acid strength for oxyacids increases as the number of oxygens attached to Y increases.
Which is more acidic, HBrO or HClO?
HClO
Acid strength for oxyacids increases as electronegativity increases
Which is a stronger base, S2- or Se2-
S2-
The corresponding acids are H2S and H2Se. Between these two binary acids, H2S is the weaker acid. The weaker the acid, the stronger the corresponding base.
The weaker the acid, the _________ the corresponding base.
stronger
For insoluble ionic hydroxides, the higher the pH, the _______ the solubility of the ionic hydroxide
Lower
For insoluble ionic compounds that contain anions of weak acids, the lower the pH, the _________ the solubility.
Higher
E.g. BaCO3 , CO3- is a weak base so it will be more soluble in an acidic solution
A solution will precipitate if Q ___ Ksp
>
greater than
