Question

What is the OH- ion concentration, in moles per liter, of an aqueous solution with a pH of 7?

Answer 1

Answer:

B

Explanation:

the pH scale is based on the function

1x10-14

So since pH is neutral the concentration of OH and H must be equal hence the only option in which the concetration would [OH]{H}= 1x10-14 would be when both are equal so it cannot be a or d and when they are expressed in concetration so the only option is B.
