Question 1

Define pH:

Answer 1

The potential of Hydrogen/ hydrogen concentration

Question 2

Hydrogen ions (H+) are extremely?

Answer 2

Question 6

Basic/Alkaline solutions have a pH of?

Answer 6

Above 7

(8-14)

Ex: Bleach

Question 7

Define Acids:

Answer 7

Solutes that ionize to release H+/Hydrogen ions

Question 8

Hydrogen Ions are referred to as Protons because?

Answer 8

Hydrogen Ions will lose their electron and only consist of a Proton

Question 9

Acids are often referred to as?

Answer 9

Proton Donors

Question 10

Define Bases:

Answer 10

Solutes that remove H+ from a solution and act a Proton Accepter

Question 11

How are water molecules formed?

Answer 11

Bases will release a Hydroxide ion (OH) that is attracted to Hydrogen Ions
