What would you predict about a chemical that has a hydrogen ion concentration of 1 × 10^−12 m?
a) it will form salt and water when added to a base.
b) it contains no hydroxide ions.
c) it has high concentration of hydroxide ions.
d) it has a sour taste.
it's not b, and i'm pretty sure that it's not c what would it be?

Option (C) is the correct answer.

Explanation:

Relation between pH and hydrogen ion concentration is as follows.

          pH =

It is given that hydrogen ion concentration is M. Therefore, putting this value in the above formula as follows.

         pH =

               =

               = - (-12) (log [1] + log[10])                 (log[1] = 0 and log[10] = 1)      

               = 12

As pH = 12, hence the solution will be highly basic. As a result, there will be high concentration of hydroxide ions.
