Question 1

Temperature affect on dissolution

Answer 1

For solids and liquids, higher temperature increases solubility, while for gases, higher temperature decreases solubility.

Question 2

Pressure affect on solubility

Answer 2

affects the solubility of gases but not solids or liquids
Higher pressure increases gas solubility.

Question 3

surface area affect on dissolution

Answer 3

none of

Question 4

Nature of Solvent and Solute

Answer 4

Polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes.

Question 5

Unsaturated Solution

Answer 5

Contains less solute than the maximum it can dissolve at a given temperature

Question 6

Saturated Solution

Answer 6

Contains the maximum amount of solute that can dissolve at a given temperature

Question 7

Supersaturated Solution

Answer 7

Contains more solute than it can theoretically dissolve at a given temperature. Usually achieved by dissolving the solute at a higher temperature and then cooling it down slowly.

Question 8

Acids properties

Answer 8

Sour taste, turn blue litmus paper red, react with metals to produce hydrogen gas, and neutralize bases.

Question 9

Bases properties

Answer 9

Bitter taste, feel slippery, turn red litmus paper blue, and neutralize acids

Question 10

Arrhenius

Answer 10

Acids produce H⁺ ions in solution, while bases produce OH⁻ ions.

Question 11

Bronsted-Lowry

Answer 11

Acids donate protons (H⁺ ions), while bases accept protons.

Question 12

Lewis

Answer 12

Acids accept electron pairs, while bases donate electron pairs.

Question 13

Conjugate acid

Answer 13

Forms when a base gains a proton.

Question 14

Conjugate base

Answer 14

Forms when an acid loses a proton.

Question 15

Answer 15

used to specify the acidity or basicity of an aqueous solution.

Question 16

strong acids

Answer 16

HI, HCl, HBr, HNO3, HClO3, HClO4, H2SO4

Question 17

strong base

Answer 17

LiOH, NaOH, KOH, Ca(OH)2, Sr(OH)2, Ba(OH)2

Question 18

strong acids and bases

Answer 18

completely dissociate in water

Question 19

weak acids and bases

Answer 19

only partially dissociate

Question 20

Answer 20

acid that contributed the anion to the salt

Question 21

parent bases

Answer 21

base that contributed the cation.
