Consider the generic acid, HA, and how it interacts with water: HA (aq) + H 2 O

Question

Consider the generic acid, HA, and how it interacts with water:

HA (aq) + H2O (l) H3O+ (aq) + A-

Consider the following statements and answer true or false.  
True False  The stronger A- is as a weak base, the stronger HA will be as a weak acid
True False  Having a greater number of electron withdrawing groups is typically the best way to stabilize a conjugate base
True False  If HA is a strong acid, A- will be a relatively strong weak conjugate base
True False  An acid with a Ka value of 1.2 x 10-4 is a weaker acid than an acid with a Ka value of 1.5 x 10-8

Explanation / Answer

False  The stronger A- is as a weak base, the stronger HA will be as a weak acid

True Having a greater number of electron withdrawing groups is typically the best way to stabilize a conjugate base

True If HA is a strong acid, A- will be a relatively strong weak conjugate base

False  An acid with a Ka value of 1.2 x 10-4 is a weaker acid than an acid with a Ka value of 1.5 x 10-8
