pH Scale

Question 1

What are the three numbers found on a pH scale?

Answer 1

0, 7, 14

Question 2

What does an acid stand for?

Answer 2

Hydrogen (H)

Question 3

What does a base stand for?

Answer 3

Hydroxide (OH)

Question 4

pH?

Answer 4

The measure of Hydrogen (H) ions

Question 5

pOH?

Answer 5

The measure of Hydroxide (OH) ions

Question 6

pH+pOH?

Answer 6

pH + pOH = 14 every time. So the H and OH no matter what, add up to 14

Question 7

What is litmus paper?

Answer 7

Litmus paper is used to measure the pH level of a substance

Question 8

What is molarity?

Answer 8

Molarity shows the amount of ions in a solution (OH - Hydroxide)

Question 9

To be an acid, the pH number has to be…?

Answer 9

Less than 7

Question 10

To be a base, the pH number has to be…?

Answer 10

More than 7

Question 11

Example

Answer 11

pH - 3 pOH - 11
Molarity of H = 1x10^-3
Molarity of OH = 1x10^-11

Question 12

Answer 12

Any species that increases the concentration of H in an aqueous solution

Question 13

Arrhenius Base

Answer 13

Any species that increases the concentration of OH in an aqueous solution
