Answer:
POH= 13
Explanation:
A student preparing for the experiments inadvertently adds an additional 400 mL of the same acid solution to the dissolution vessel. What will be the new pOH of this solution?
PH is the measure of the degree of acidity of a solution.
POH is the measure of the degree of alkalinity of a solution
Note that pH + pOH = 14
if concentration remains the same, then volume changes will not affect pH.
The pH of the solution is given as
PH= -log[H+].
For this experiment, the dissolution vessel contains 0.1 M HCl, no matter the initial volume of the acid solution
For the molar concentration of the cation, we can propose that a strong acid will dissociate completely,
[H+] = 0.1 = 1 x 10-1 M
. substituting the concentration of the cation
PH=-log[1 x 10-1] = 1.
Note that pH + pOH = 14 for any aqueous solution.
we say that
the pOH = 14 - pH.
pOH = 14-1 = 13.
