The actual answer is 7.58, sorry...

When A solution at 25 degrees Celsius has a pOH of 6.42. So here the pH of the solution is 7.58.

Calculation of the pH of the solution?

Since we know that

pH + pOH = 14

here

pOH is 6.42

So,

pH = 14 - pOH

= 14 - 6.42

= 7.58

hence, When A solution at 25 degrees Celsius has a pOH of 6.42. So here the pH of the solution is 7.58.
