Q

If Ksp < Q

A

more reactants than products; shift right

Q

If Ksp> Q

A

More products than reactants; shift left

Q

if Q = Ksp

A

The system is in equilibrium

Q

Larger Ka = ______ conjugate base

A

weak

Q

Weak Ka= _________ Conjugate base

A

Stronger

Q

What is the Ka value for HCl

A

VERY large

Q

Larger the Ka, _______ the pH

A

Closer to 0 the pH is

Q

Higher the Ka, the ___________ the acid

A

stronger
