Students in a science class learn that groundwater is an important source of drinking water for many communities. They construct

a model to study how leaking chemicals from a landfill can affect groundwater.
What is the most effective way for the students to see how leaking chemicals from a landfill can enter a well?


A.Tilt the tank towards the well and drain some of the water out of the tank.

B.Drop food color into the well at the well's opening.

C.Tear some of the colored tissue paper and put the paper pieces into the well at the well's opening.

D.Pump water out of the well to see how stained water from the tissue paper moves toward the well.

A student prepares a 0.47mM aqueous solution of acetic acid CH3CO2H. Calculate the fraction of acetic acid that is in the dissoc
Aliun [14]

The fraction of acetic acid that is dissociated is 0.18

Why?

The chemical equation for the dissociation of acetic acid (HAc) is the following:

HAc(aq) + H₂O(l) ⇄ H₃O⁺(aq) + Ac⁻(aq)

To find the fraction of acetic acid that is in the dissociated form (f), we apply the following equation (Ka for acetic acid is 1.76*10⁻⁵). This equation comes from solving the equation of the equilibrium constant for the dissociated fraction of HAc:

f=\frac{-Ka+\sqrt{Ka^{2} +4KaC} }{2C} = 0.18

Have a nice day!
