Unit 12

Question 1

It can increase H+ ion concentration in an aqueous solution

Answer 1

Arrhenius acid

Question 2

It can increase OH- ion concentration in an aqueous solution

Answer 2

Arrhenius base

Question 3

It can donates a proton (H+)

Answer 3

Bronsted Lowry acid

Question 4

It can accept a proton (H+)

Answer 4

Bronsted Lowry base

Question 5

Acids are the hydrogen-containing compounds which give H+ ions or protons on dissociation in water and bases are the hydroxide compounds which give OH− ions on dissociation in water.

Answer 5

Dissociation

Question 6

An acid is a proton (H⁺) donor, and a base is a proton acceptor. When a Bronsted–Lowry acid loses a proton, a conjugate base is formed. Similarly, when a Bronsted–Lowry base gains a proton, a conjugate acid is formed.

Answer 6

Ionization

Question 7

A conjugate acid is formed when a proton is added to a base, and a conjugate base is formed when a proton is removed from an acid.

Answer 7

Conjugate acids/bases

Question 8

An acid that contains two hydrogen atoms

Answer 8

Diprotic acid

Question 9

An acid that contains more than two hydrogen atoms

Answer 9

Polyprotic acid

Question 10

An aqueous cation

Answer 10

Hydronium

Question 11

The acidity or alkalinity of a solution

Answer 11

Strength

Question 12

the quantity of a solute that is contained in a particular quantity of solvent or solution

Answer 12

Concentration

Question 13

Reactivity of a substance with both acids and bases, acting as an acid in the presence of a base and as a base in the presence of an acid

Answer 13

Amphoteric

Question 14

a substance that can both accept and donate a proton or H+. It has characteristics of both and acid and a base and can act as either

Answer 14

Amphiprotic

Question 15

The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7. The pOH is convenient to use when finding the hydroxide ion concentration from a solution with a known pH.

Answer 15

pH and pOH

Question 16

Nonmetal oxides that react with water to form acids

Answer 16

Acid anhydride

Question 17

Metal oxides that react with water to form bases

Answer 17

Base anyhydride

Question 18

Dissolve in water react with water to form basic solutions

Answer 18

Metal oxide

Question 19

Dissolve in water react with water to form acidic solutions

Answer 19

Nonmetal oxide

Question 20

A process in which water molecules break down a compound

Answer 20

Hydrolysis

Question 21

A salt that contains H+ cation

Answer 21

Parent acid

Question 22

A salt that contains OH- anion

Answer 22

Parent base

Question 23

When an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.

Answer 23

Neutralization

Question 24

the process of determining the concentration of a dissolved substance in terms of the smallest amount of a reagent of known concentration required to bring about a given effect in reaction with a known volume of the test solution

Answer 24

Titration

Question 25

Substances whose solutions change color due to changes in pH.

Answer 25

Indicator
