At `50^(0)C, pH + pOH` is

Which of the following is wrong (A) At any temperature pH of H_(2)O is exactly equal to 7 (B) At 25^(0)C ,the pH of an acid is less than 7 (C) At 25^(0)C ,the pH of a base is greater than 7 (D) At 25^(0)C ,the "pOH" of water is equal to 7

What will be the pOH of a neutral solution at 50^(@)C if its pK_(w) is 13.38 at 50^(@)C .

In 0.02 M solution of perchlorid acid (HClO_(4)) at 298 K the sum of pH and pOH is equal to

The pKw of water at 50^@C is 13.40. An aqueous solution at 50^@C has pH= 7. This solution is–

The relation between pH and pOH is

Solution of equal of pH and pOH is called
