Question 1

Dissociation

Answer 1

The separation of ions that occurs when an ionic compound dissolves.
Ex. CaCl_3(s) —-> Ca^2+(aq) + 2Cl^-(aq)

Question 2

Molarity

Answer 2

An expression of concentration; moles of solute per liter of solution (M)

Question 3

Solution

Answer 3

A homogeneous mixture of two or more substances; mol = M • L

Question 4

Vapor pressure

Answer 4

The pressure exerted by a vapor in equilibrium with its liquid or solid phase

Question 5

Specific heat capacity

Answer 5

The amount of heat energy required to raise the temperature of one gram of substance by one degree Celsius.
C = q/Mx🔺T

Question 6

Acid

Answer 6

A proton (H+) donor

Question 7

Base

Answer 7

A proton (H-) acceptor

Question 8

pH

Answer 8

A measure of acidity; pH = -log[H+]

Question 9

Hydronium ion

Answer 9

Formed when water bonds with a proton donated from an acid, H3O-

Question 10

Amphoteric

Answer 10

Able to act as both an acid and a base

Question 11

Neutralization Rx

Answer 11

A reaction between an acid and a base

Question 12

Polyprotic

Answer 12

An acid that can donate multiple protons

Question 13

Buffer solution

Answer 13

A solution that resists change in pH; contains a weak acid and its conjugate base.

Question 14

Henderson-hasselbalch equation

Answer 14

Used to calculate the pH of a buffer solution .

pH= pKa + log[conj base]/[acid] ; pOH = pKb + log [conj acid]/ [base]

Question 15

Buffering capacity

Answer 15

The amount of acid or base that the buffer can neutralize before the pH begins to change appreciably

Question 16

Thermodynamics

Answer 16

The study of energy changes

Question 17

First law of thermodynamics

Answer 17

Energy is neither created or destroyed in ordinary chemical reactions and physical changes

Question 18

Calorie

Answer 18

Amount of heat energy required to raise the temperature of one gram of water by one degree Celsius.
