Urinalysis and Urine Microscopy | Abdominal Key

Urinary pH. Urine pH reflects the degree of acidification of urine; hence it is a measure of the urine hydrogen ion concentration. Urine pH normally ranges from 4.5 to 8.0 based on the prevailing systemic acid-base balance. Examination of urine pH is most useful in the workup of a metabolic acidosis.

Gemstone Density: The Definitive Guide at AJS Gems

The density is expressed as a number which indicates how much heavier the gemstone is compared to an equal volume of water. Most gemstone varieties are 2 to 4 times denser than a equal volume of water. But the range is quite wide -- from 8 for cinnabar to 1 for amber. Diamond, at 3.50 to 3.53, falls approximately in the middle. See also:
