Question 3

A solution must have a pH of what to be a base?

Answer 3

pH of 7.1 - 14

Question 4

A solution must have a pH of what to be a neutral?

Answer 4

pH of 7

**however a neutral can be from 6-8 since 6 is a weak acid and 8 is a weak base.

Question 5

What is an example of a weak base? (pH scale number)

Answer 5

pH of 8

Question 6

What is an example of a strong base? (pH scale number)

Answer 6

pH of 14

Question 7

What is an example of a weak acid? (pH scale number)

Answer 7

Question 8

What is an example of a strong acid? (pH scale number)

Answer 8

pH of 1

Question 9

What does the pH scale focus on/how is it determined?

Answer 9

pH focuses on concentrations of hydrogen ions (H+) and hydroxide ions (OH-)

Question 10

What does the pH scale go from and end at?

Answer 10

Values very close to 0 through 14

Question 11

If there are more OH-, what does that indicate?

Answer 11

More basic

Question 12

If there are more H+, what does that mean?

Answer 12

More acidic
