Solution
To find the concentrations of
and
in moles per liter for the substances with the given pH values, we can use the relationship between pH and the concentration of hydrogen ions (
):
From this equation, we can solve for
:
Once we have
, we can use the equation
to find
.
Let’s calculate the concentrations for each pH value:
Now, using the relationship between
and
:
So, the concentrations of
and
in moles per liter for the substances with the given pH values are:
