Mercury is often released into water bodies with industrial effluents, where it is then converted to the compound form methylmercury. methylmercury is easily absorbed by aquatic organisms. research suggests that the presence of mercury seriously decreases the reproductive rate of fish-eating birds, like heron, and causes other notable harmful effects. on the other hand, the small fish on which the herons prey are not significantly affected. explain why the toxic effects of mercury is significant in herons, but not in the fish they eat.

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
