Explanation:
The value of :
a. pOH = 3.51
The sum of pH and pOH is equal to 14.
pH + pOH = 14 (at 25°C)
pH = 14 - 3.51 = 10.49
The pH of the solution is defined as negative logarithm of hydrogen ion concentration in solution.
is the
concentration for an aqueous solution with pOH = 3.51 at 25°C.
b.
At a certain temperature, the pH of a neutral solution is 7.56.
Neutral solution means that concentration of hydrogen ion and hydroxide ions are equal.
The value of at at this temperature:
The value of at at this temperature is
