Question

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 so... What would it be?

Answer 1

B is right hope it helped.

Answer 2

Answer: Option (C) is the correct answer.

Step-by-step explanation:

Relation between pH and hydrogen ion concentration is as follows.

pH =
`-log[H^(+)]`

It is given that hydrogen ion concentration is
`1 * 10^(-12)` M. Therefore, putting this value in the above formula as follows.

pH =
`-log[H^(+)]`

=
`-log[1 * 10^(-12)]`

= - (-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.
