Question 15

Introduced the classifications of substances as hard and soft acids and bases

Answer 15

R.G. Pearson

Question 16

AQUAHYD-IC
OXO-ENRES

Answer 16

In general, acids are identified as hard or soft by the thermodynamic stability of the complexes they form

Question 17

Hard acid: smaller size, greater charge
Soft acid: greater size, smaller charge

Answer 17

Polarization refers to the tendency of anion to be polarized. The greater size, more polarizable. Therefore,

Hard: less polarizable
Soft: more polarizable

Question 18

Polarizing power:

Question 19

Polarizing power: power of cation to polarize anion. Therefore

Answer 19

Hard: more polarizing
Soft: less polarizing

Question 20

Factors that affect polarization. Fajans Rule

Answer 20

CAT ANnoys CHA and ELle

Question 21

Factors that influence acidity

Answer 21
