IPS Chemical Interactions Chapter 3 Section 4

Question 1

acid

Answer 1

any substance that produces hydrogen ions (H+) in water

Question 2

base

Answer 2

any substance that produces hydroxide ions (OH-) in water

Question 3

pH scale

Answer 3

a numeric scale used to describe the concentration of ions

Question 4

Neutralization

Answer 4

a reaction between an acid and a base

Question 5

salt

Answer 5

any ionic compound that can be made from the neutralization of an acid with a base

Question 6

Hydrogen ion (H+)

Answer 6

an atom of hydrogen that has lost its electron; Hydrogen ions are the key to the reaction of
acids

Question 7

Hydroxide ion (OH-)

Answer 7

a negative ion made of oxygen and hydrogen; when bases dissolve in water, the positive ions and hydroxide ions separate

Question 8

What does the “p” in pH scale refer to?

Answer 8

the power, or exponent, used in measuring ion

concentrations

Question 9
