3. With at least two reasons, explain how "acid mine drainage" can pollute the environment. 1pts 4. 10.0 g of soil were shaken with 100.0 mL of 1 M ammonium acetate, allowed to stand for 2 hours, and filtered. 20.00 mL of the filtrate was taken and found to have mass mixing ratios of 200 ppm Ca 180 ppm Mg2+, and 270 ppm K+. The concentration of Na was below the detection limit. What is the cation exchange capacity (CEC)ofthe soil (in units of cmol kg i)? Assume a base saturation of 100% and a water density of 1.00 g/mL. 3pts 5. A platinum indicator electrode was immersed in topsoil and a voltage of0.855 V(relative to a standard hydrogen electrode) was measured 2pts A) Calculate the pE value of the soil. Assume a temperature of 25 oC B) Calculate the equilibrium ratio of Fe3+ to Fe2 The standard reduction potential (EO) for Fe3+/Fe2 is 0.771

Explanation / Answer

ANS3. what is acid mine drainage(AMD):-It is formed by the reaction between the water and rock contaning sulfur . It especially occurs in metal mines and coal mines. This acid is carried off the mine site by rainwater or surface drainage and gets to the nearby streams, rivers or lakes, creating environmental risks.

It pollutes the environment

reasons:-

(a) It may disturb the reproduction system of aquatic life such as fish and thus may decrease their population.

(b) It also affects the infrastructure by corrosion.

(c) it affects the PH of environment.
