What is the ph of a 6.4 x 10^-10 m oh- solution

pH of the solution is 4.81

Explanation:

pH is defined as the negative logarithm of hydrogen or hydronium ion concentration. It is basically the power of hydrogen ions.

Mathematically,

We are given:

To calculate pH, we first calculate pOH of the solution and then subtract it from 14.

Putting the value of hydroxide ion concentration in above equation, we get:

Now, using the below equation:

Hence, pH of the solution is 4.81
