Explain Properties of Urine .​

Answer 1

$\huge{\boxed{\boxed{\mathfrak{\red{Answer}}}}}$

Major components of urine

Urea (also known as carbamide) is a waste product of many living organisms, and is the major organic component of human urine. This is because it is at the end of chain of reactions which break down the amino acids that make up proteins. These amino acids are metabolised and converted in the liver to ammonia, CO2, water and energy.

Properties

Colour: Typically yellow-amber but varies according to recent diet and the concentration of the urine. Drinking more water generally tends to reduce the concentration of urine, and therefore cause it to have a lighter colour. (The converse is also true.)

Smell: The smell (or "odour", which is the more clinical term, American spelling "odor") of urine may provide health information. For example, urine of diabetics may have a sweet or fruity odour due to the presence of ketones (organic molecules of a particular structure). Generally fresh urine has a mild smell but aged urine has a stronger odour, similar to that of ammonia.

Acidity: pH is a measure of the acidity (or alkalinity) of a solution. The pH of a substance (solution) is usually represented as a number in the range 0 (strong acid) to 14 (strong alkali, also known as a "base"). Pure water is "neutal" in the sense that it is neither neither acid nor alkali, it therefore has a pH of 7. The real significance of pH in terms of physical chemistry is that pH is a measure of the activity of hydrogen ions (H+) in a solution.

Answer 2

Explanation:

Physical characteristics that can be applied to urine include color, turbidity (transparency), smell (odor), pH (acidity – alkalinity) and density. ... Color: Typically yellow-amber, but varies according to recent diet and the concentration of the urine.
