Here are the answers to the questions:
b) pH of 13 than pH of 8?
pH 13 is more basic (or a stronger base) than pH 8. The student's answer "stronger" is correct in this context.
5) Place the following labels on the pH scale below:
Here is how the labels should be placed on the pH scale:
Far left end of the scale (where the student wrote '7'):
The number should be $\boxed{\text{0}}$
Above this point: $\boxed{\text{Strongest acid}}$
The region from 0 to just below 7 (under the left bracket): $\boxed{\text{Acids}}$
Below the arrow pointing left from 7: $\boxed{\text{More acidic}}$
Middle of the scale (at '7'):
The number is $\boxed{\text{7}}$
Above this point: $\boxed{\text{Neutral}}$
Far right end of the scale (at '14'):
The number is $\boxed{\text{14}}$
Above this point: $\boxed{\text{Strongest base}}$
The region from just above 7 to 14 (under the right bracket): $\boxed{\text{Bases}}$
Below the arrow pointing right from 7: $\boxed{\text{More basic}}$
