Ammonia is approximately 3 times more toxic than urea in terms of acute toxicity. Urea is less toxic to aquatic organisms compared to ammonia because it undergoes nitrification in water, converting it to nitrate which is less toxic.

What is more toxic nitrate or ammonia?

Ammonia is typically more toxic than nitrate to aquatic organisms. Ammonia is highly toxic to fish even at low concentrations, while nitrate is less acutely toxic but can still be harmful at high levels, leading to issues like algae blooms. Both compounds can negatively impact water quality and aquatic ecosystems.


Why ammonia is more toxic than urea?

Ammonia is more toxic than urea because it is a strong alkaline compound that can disrupt cellular processes and cause damage to tissues and organs. Urea, on the other hand, is a less toxic waste product that is more easily excreted by the body in urine.


Is uric acid more toxic than ammonia?

Uric acid is less toxic than ammonia. Ammonia is highly toxic to the body and can cause damage to cells and organs. Uric acid, on the other hand, is a waste product formed from the breakdown of purines and is usually excreted by the kidneys in the urine.


Is the ammonia molecule the most toxic to cells?

Ammonia is toxic to cells at high levels as it disrupts cellular processes and can lead to cell damage or death. However, there are other molecules that can be more toxic to cells depending on the concentration and exposure duration.


How many more times is ammonia more basic than baking soda?

Ammonia is about 1000 times more basic than baking soda. This is because the pH of a 1 M solution of ammonia is around 11.6, while the pH of a 1 M solution of baking soda is around 8.4.


Is Ammonia poisonous to humans?

Yes, ammonia is poisonous to humans, but only in large quantity. When ammonia is used as a dilute solution in water (as a cleaning agent, for example) it is not dangerous. Pure ammonia is approximately as toxic as chlorine gas.


If human urine is allowed to stand for sometime it semelles strongly of ammonia . why?

Urea is a non-toxic molecule made of toxic ammonia and carbon dioxide that is found in Urine. Dehydration causes your urine to be more concentrated and may have a stronger smell than normal,


A nitrogenous waste that is less toxic than ammonia?

Urea is a nitrogenous waste that is less toxic than ammonia. It is produced in the liver as a byproduct of protein metabolism and is excreted by the kidneys in urine. Urea requires less water to be excreted compared to ammonia, making it a more efficient waste product for terrestrial animals.


Is urea more toxic thzn ammonia?

Urea is typically less toxic than ammonia. Ammonia is a direct irritant to the respiratory system and can cause damage upon inhalation, while urea is less likely to cause immediate harm. However, both substances can be harmful in high concentrations and should be handled with caution.


The advantage of excreting wastes as urea rather than as ammonia is that?

Urea is less toxic than ammonia, making it safer to store in the body before excretion. It also requires less water to eliminate compared to ammonia, making it more energy-efficient for terrestrial animals. Additionally, the conversion of ammonia into urea consumes less energy, resulting in a net energy savings for the organism.


Why is lead hydroxide not preferred as an alkali for the preparation of ammonia?

Lead hydroxide is not preferred as an alkali for the preparation of ammonia because it is a toxic substance and poses serious health hazards. Additionally, lead hydroxide can react with ammonia to form toxic lead compounds, further complicating the process. It is safer and more efficient to use other alkalis such as sodium or potassium hydroxide for this purpose.


Is hippuric acid more toxic than ammonia?

Hippuric acid is generally considered to be less toxic than ammonia. Ammonia is a highly toxic compound that can cause severe neurological damage and other health issues even at relatively low concentrations. In contrast, hippuric acid is a metabolite of the amino acid glycine and is usually excreted in urine without significant harmful effects. However, high levels of hippuric acid can indicate exposure to certain toxins, but its direct toxicity is not comparable to that of ammonia.
