What is chemical name of urea?
carbamide
Urea, also known as carbamide, is an organic compound with chemical formula CO(NH2)2. This amide has two –NH2 groups joined by a carbonyl (C=O) functional group.
Is urea made from urine?
Urea, also known as carbamide, is a safe, useful compound with a significant history. It is a naturally occurring molecule that is produced by protein metabolism and found abundantly in mammalian urine.
What is urea fertilizer?
Urea is a source of Nitrogen, an essential nutrient crucial for crop growth and development. Urea is the most important nitrogenous fertilizer in the country because of its high N content (46%N). It also has industrial applications such as the production of plastics and as a nutritional supplement for cattle.
What is the formula for urine?
Urine is an aqueous solution of greater than 95% water, with a minimum of these remaining constituents, in order of decreasing concentration: Urea 9.3 g/L. Chloride 1.87 g/L. Sodium 1.17 g/L.
What is urea normal range?
In general, around 6 to 24 mg/dL (2.1 to 8.5 mmol/L ) is considered normal. But normal ranges may vary, depending on the reference range used by the lab and your age. Ask your doctor to explain your results. Urea nitrogen levels tend to increase with age.
What’s the pH of urea?
The conductance method using four acid concentrations ex- tending from 4.56 X l0 -4 to 9.13 X 10 -4 M PNP in 9.44 M urea yielded an average pK of 6.19. The measured pH of a 0.05 M equimolar buffer of PNP and its sodium salt was 7.84. These results are entirely consistent with those obtained on the acetic acid system.
What does it mean if your urea is high?
A high urea value can mean kidney injury or disease is present. Kidney damage can be caused by diabetes or high blood pressure that directly affects the kidneys. High urea levels can also be caused by low blood flow to the kidneys caused by dehydration or heart failure.
Which urea is best?
– Urea fertilizer provides nitrogen, which promotes green leafy growth that not only makes your garden look lush, but is also important for photosynthesis.
How often should urea be applied?
Soluble fertilizers, for instance, are applied every two weeks during the growing season. Granular fertilizers are generally applied about every six to eight weeks. Slow-release fertilizers work for months, so one application is generally all that is needed for a growing season.
What is normal content of urine?
Sample preparation. Human urine is composed primarily of water (95%). The rest is urea (2%), creatinine (0.1%), uric acid (0.03%), chloride, sodium, potassium, sulphate, ammonium, phosphate and other ions and molecules in lesser amounts30 (Table 1).
What is a healthy urine pH?
Normal Results The normal values range from pH 4.6 to 8.0. The examples above are common measurements for results of these tests. Normal value ranges may vary slightly among different laboratories.
