?STUDY ON PHYSICAL PROPERTIES OF URINE-OXALIC ACID MIXTURE
Keywords:
Urine-oxalic acid, Physical properties, Density, Viscosity.Abstract
Physical properties namely density, viscosity, surfacetension andpHofoxalic acid-urinesystem havebeen Determined.
The results may be summarized as (i)Density decreases with increasein concentrationof oxalic acid in urine-oxalic acid
mixture (ii) Surface tension first increases and then decreases with increase of oxalic acid (iii) Viscosity of urine-oxalic
acid mixture increases and then decreases with increase in concentrationof oxalic acid but viscosity of urine-oxalic acid
mixture is lower than that of urine (iv)pH decreases with increase of concentration of oxalic acid in urine. (v)Tempera-
tureofmixing increaseswith increaseofconcentrationofoxalicacidinurine.Sinceoxalic acidiswellknown forits stone
forming tendency, its occurrence in urine in different proportions bears special significance. In view of these, physical
properties measurements havebeenused toexplain unusualbehaviourof urine-oxalic acid systemand intraction ofurine
with bladder interface.
