If the (H+) is 2.1×10^-12 MHCIO4, What is the PH? is the solution ACIDIC, BASIC or NEUTRAL.​
Lilit [14]

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 \times  {10}^{ - 12} )  \\  = 11.6777807 \:  \:  \:  \:  \:  \:

We have the answer as

<h2>pH = 11.7 </h2>

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

Hope this helps you
