Acids and Bases Quiz 1

Question 1

What is an Arrhenius acid?

Answer 1

a hydrogen- containing compound, that when dissolved in water, produces hydrogen ions
acidic species is H+

Question 2

What is an Arrhenius base?

Answer 2

a hydroxide ion- containing compound that, when dissolved in water, produces hydroxide ions (OH-)
basic species is OH-

Question 3

Arrhenius acids in the pure state are

Answer 3

covalent compounds- do not contain H+ ions

Question 4

ionization

Answer 4

ions are produced from a molecular compound when it is dissolved in a solvent

Question 5

Arrhenius bases are what compounds in the pure state

Answer 5

ionic compounds in the pure state- already contain OH-

Question 6

dissociation

Answer 6

already existent ions in an ionic compound separate when it is dissolved in water

Question 7

What is a Bronsted- Lowry acid?

Answer 7

any substance that can donate a proton (H+) to another substance

Question 8

What is a Bronsted- Lowry base?

Answer 8

any substance that can accept a proton (H+) from some other substance

Question 9

What are the shortcomings of Arrhenius acid theory?

Answer 9

restricted to aqueous solutions

does not explain why some compounds like NH3, which do not contain OH-, are able to produce basic aqueous solutions

Question 10

How can a B-L base that already has hydrogen atoms in its formula accept more hydrogen atoms?

Answer 10

bases have at least one pair of electrons for H+ to go

Question 11

What is the acidic species in B-L theory?

Answer 11

H3O+

Question 12

Why is H+ a proton?

Answer 12

lost its lone electron
