Q: The amount of water required for the removal of 2 g of ammonia is;
a.200 ml
b. 500 ml
c. 100 ml
d. 1000 ml

Answer 1

Answer:

For removal of 2g of ammonia, 1000ml of water is required.

Explanation:

• Ammonia is the most toxic waste substance that is found in ammonotelic organisms ( the animals that excrete nitrogenous waste within the form of ammonia) such as protozoa, fishes, amphibians, platyhelminthes etc. Generally, ammonia is excreted by aquatic animals. If there is enough water available, ammonia, a small molecule, can easily diffuse across skin and gills. However, the kidneys are ineffective at eliminating ammonia.

• Ammonia requires the maximum amount of water for its removal among the three waste forms: Ammonia, uric acid and urea.

• 1 gram of ammonia requires 300-500ml of water therefore 2g of ammonia will require 600-1000 ml of water. So, for 2g ammonia removal, 1000 ml water is required.

Hence, the correct option is (d).
