Where Ka is the dissociation constant of the acid.
pKa of phenolphthalein = 9.40
pH = 10.9
So,
Answer:
The ration of molar concentration is "2.5".
Explanation:
The given values are:
Average density of salt water,
=
Net pressure,
=
Increase in pressure,
=
Now,
The under water pressure will be:
=
=
=
=
hence,
The ratio will be:
=
or,
=
=
=
