Answer:
Approximately (assuming that the solution is at
, under which
.)
Explanation:
Let and
denote the concentration of
and
respectively.
Let denote the self-ionization constant of water. The exact value of
depends on the temperature of the solution.
at
.
The product of and
in a solution (with
, or moles per liter, as the unit) is supposed to be equal to the
value of that solution at the corresponding temperature. In other words:
.
Rearrange to obtain an expression for :
.
Assume that the solution in this question is at (for which
.) For this solution:
.
Hence, the of this solution would be:
.
