Freezing point of urine
WebSo, first we gotta figure out the freezing point of urine. Issue is, it ain't just water. There's salts, urea so it's different. Plus, this is gonna depend on each person and their diet, level of activity, age, sex, metabolic factors, genetic factors etc. So, let's assume it's a normal person, drinks good amount of water. WebThe freezing point depression osmometer is an osmometer that is used in determining a solution's osmotic concentration as its osmotically active aspects depress its freezing point. ... Urine osmolality is also used to measure urine concentration accurately and thus determine renal function and body fluid homeostasis. Evaluation of its use
