1
Q

The stronger the acid, the _______ the conjugate base

A

weaker

2
Q

What are the 6 strong acids?

A

HCl

HBr

HI

HClO4

H2SO4

HNO3

3
Q

Cations that are small and highly charged (3+) are always ___________________

A

Acidic

4
Q

For binary acids, acidity increases to the ______ and _________ on the periodic table

E.g. HCl > HF

A

right, down

5
Q

Which is more acidic, H2SO4 or H2SO3?

A

H2SO4

Acid strength for oxyacids increases as the number of oxygens attached to Y increases.

6
Q

Which is more acidic, HBrO or HClO?

A

HClO

Acid strength for oxyacids increases as electronegativity increases

7
Q

Which is a stronger base, S2- or Se2-

A

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.

8
Q

The weaker the acid, the _________ the corresponding base.

A

stronger

9
Q

For insoluble ionic hydroxides, the higher the pH, the _______ the solubility of the ionic hydroxide

A

Lower

10
Q

For insoluble ionic compounds that contain anions of weak acids, the lower the pH, the _________ the solubility.

A

Higher

E.g. BaCO3 , CO3- is a weak base so it will be more soluble in an acidic solution

11
Q

A solution will precipitate if Q ___ Ksp

A

>

greater than
