A buffered solution containing dissolved aniline, C 6 H 5 NH 2 , and aniline hydrochloride, C 6 H 5 NH 3 Cl , has a pH of 5.34 . A. Determine the concentration of C 6 H 5 NH 3 in the solution if the concentration of C 6 H 5 NH 2 is 0.245 M. The p K b of aniline is 9.13.

Answer : The  concentration of is, 0.0830 M

Explanation : Given,

Concentration of = 0.245 M

pH = 5.34

First we have to calculate the value of pOH.

Now we have to calculate the concentration of

Using Henderson Hesselbach equation :

Now put all the given values in this expression, we get:

Therefore, the concentration of is, 0.0830 M

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
