The Effect of Structure on Acid-Base Properties

Question 1

What is an oxyacid/oxoacid?

Answer 1

Acids that contain hydrogen, oxygen and another element

Question 2

1st rule for oxyacids

Answer 2

For any central atom, the strength increases with the number of oxygen attached

Question 3

2nd rule for oxyacids

Answer 3

When central atoms are in same group and same number of oxygen attached..
- Strength increases from bottom to top

Question 4

3rd rule for oxyacids

Answer 4

When same number of oxygen are attached to central atom…
- Strength increases from left to right

Question 5

What else does it indicate when an atom has a good ability to draw electrons towards itself?

Answer 5

• The greater the acidity of the molecule
• Will be molecules with higher electronegativity

Question 6

1st rule for strength of binary acids

Answer 6
