Question

The pH of human blood is slightly basic. Which of the following is most likely to be the pH of human blood?

(A) 10.6
(B) 7.4
(C) 7.0
(D) 6.4
(E) 4.6

Answer 1

B: basic is any number between 7 and 14. Therefore, D and E can not be correct. C cannot be correct because 7.0 even is neutral. A cannot be the answer because human blood is only slightly basic. 10.6 is too far above 7 to be considered "slight". Therefore, the answer is B.

Answer 2

the answer is b. A neutral pH is 7. Basic>7 and Acidic<7.
