question 1
a floor cleaner was found to have a ph of 13, we would consider this to be highly...
a acrid
b basic
c acidic
d plain

Explanation:

The pH scale ranges from 0 to 14. A pH less than 7 is acidic, equal to 7 is neutral, and greater than 7 is basic. A pH of 13 is greater than 7, so the floor cleaner is highly basic. Option A "acrid" refers to a sharp smell, not pH. Option C "acidic" is for pH < 7. Option D "plain" is irrelevant. So the correct answer is B.

Answer:

B. basic
