Question

If the (H+) is 2.1×10^-12 MHCIO4, What is the PH? is the solution ACIDIC, BASIC or NEUTRAL.​

Answer 1

Step-by-step explanation:

The pH of a substance can be found by using the formula

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

where [ H+ ] is the hydrogen ion concentration in the substance

From the question

[ H+ ] = 2.1 × 10-¹² M

To find the pH substitute the value into the above formula

We have

`pH = - log(2.1 * {10}^( - 12) ) \\ = 11.6777807 \: \: \: \: \: \:`

We have the answer as

pH = 11.7

The solution is basic since it lies in the basic region that is from 8 to 14

Hope this helps you
