pH

Question 1

True or False:

Hydrogen and hydroxide ions not reactive.

Answer 1

False:

They are very reactive.

Question 2

Acid:

Answer 2

A compound that donates hydrogen ions to a solution. An acidic solution has a higher concentration of H+ than OH-.

Question 3

Base:

Answer 3

A compound that accepts hydrogen ions and removes the from the solution. The more basic a solution is the higher its OH- concentration and the lower its H+ concentration.

Question 4

pH scale:

Answer 4

A scale used to determine how acidic or basic a solution is.
pH stands for POTENTIAL OF HYDROGEN.

Question 5

What is a buffer?

Answer 5

A substance that minimizes the changes in pH.

Example:
Sodium Bicarbonate

Question 6

Acid Precipitation:

Answer 6

Rain, snow, or fog with a pH lower than 5.6.

Question 7

Hydrogen ions (H+) and hydroxide ions (OH-).

Answer 7

When ions form as a result of breaking apart from the aqueous solution they form hydrogen ions (H+) and hydroxide ions (OH-).
