Module #7: Acid/Base Equilibria

Question 1

pH = ?

Answer 1

pH = -log ([H3O+])

Question 2

What is the water ionization constant?

Answer 2

Kw = [H3O+] x [OH-] = 1 x 10 to the -14th power M squared

Question 3

pOH = ?

Answer 3

pH = -log ([OH])

Question 4

pH + pOH = ?

Answer 4

pH + pOH = 14

Question 5

What are some strong acids

Answer 5

HCl - HBr - HI - HNO3 - HClO4 - H2SO4

Question 6

How can you tell a strong base?

Answer 6

If it is an ionic compound with a Hydroxide (OH), and if it is soluble

Question 7

What is the relation between Ka and Kb?

Answer 7

Ka x Kb = Kw

Question 8

Arrhenius definition of acids and bases

Answer 8

An acid is any substance that increases the concentration of H3O+ in water, and a bass is any substance that increases the OH- concentration in water

Question 9

Lewis Definition of Acids and Basses

Answer 9

Acids are substances that accept a lone pair of electrons, while basses are substances that donate a lone pair of electrons.
