Question

6. With regard to the pH scale, a solution with a pH A. close to 14 is considered a strong base. B. of 6 is considered neutral. C. higher than 7 is considered an acid. D. lower than 7 is considered basic.

Answer 1

Because a pH of 7 is neutral, we can eliminate answer B.

A pH of 8-14 is a base, and a pH of 1-6 is an acid, meaning that C and D aren't right.

Because a solution with a pH of 14 falls into the right category of being a strong base, A seems to be the right answer!

Answer 2

B can be cross out because 7 is considered neutral.
C is also wrong because it should be lower to become more acidic.
D is also wrong because the anything above 7 is basic.

So A is your answer, hope it helped :D
