Acid Base Review

According to Arrhenius, what is the definition of an ACID?

• a substance that contains hydroxide and ionizes to produce OH-

• a substance that contains hydrogen and ionizes to produce H+

• a substance that contains hydrogen and ionizes to produce OH-

• a substance that contains hydroxide and ionizes to produce H+

What is being donated/accepted between conjugate acid-base pairs?

• a hydrogen (H+) ion

• a hydroxide (OH-) ion

• water

• a neutron

What is the conjugate acid in the following equation?

• PO₄^3- 

• HNO₃ 

• NO₃^- 

• HPO₄^2-
  

Which of the following acids has a pKa value of approximately -10?

• HCl

• H2SO4

• CH3COOH

• H3PO4

Match each pH with the correct category:

• 7.0

• neutral

• 1.0

• strong acid

• 8.5

• weak base

• 5.5

• strong base

• 13.5

• weak acid

Match the following

• Nitric Acid

• H₂SO₄

• Sulfuric Acid

• HNO₃

• Calcium Hydroxide

• HCl

• Sodium Hydroxide

• Ca(OH)₂

• Hydrochloric Acid

• NaOH

Which of the following shows the correct conjugate acid base pair?

• HCI (acid) / H₃O⁺ (conjugate base)

• HCI (acid) / CI^- (conjugate base)

• HCI (base) / CI^- (conjugate acid)

• HCI (base) / H₃O⁺ (conjugate acid)

Strong acids and bases...

• do not break apart into ions (non-electrolyte)

• partially break apart into ions (weak electrolyte)

• completely break apart into ions (non-electrolyte)

• completely break apart into ions (strong electrolyte)

What are the weak acids and bases?

• all acids and bases are weak

• if not classified as strong, the acid/base is considered weak

• all acids and bases are strong

• there are more strong acids and bases than there are weak acids/bases

According to Bronsted-Lowry, what is the definition of an BASE?

• a substance that donates a hydrogen (H+) ion

• a substance that donates a hydroxide (OH-) ion

• a substance that accepts a hydrogen (H+) ion

• a substance that accepts a hydroxide (OH-) ion
