Question

Concentration of inorganic salts in normal urine of a human being is
A. 0.15%
B. 0.25%
С. 1.5%
D. 2.5%

Answer 1

Hint: A salt that does not contain C-H bonds is called inorganic salts. One of the common salts is sodium chloride, which is a chemical compound composed of sodium and chloride ions.

Complete answer:
Urine is a by-product of metabolism in humans and also in many other animals. Urine flows from kidneys through the ureters to the urinary bladder. Human urine consists of 91% to 96% of water with organic solutes like urea, creatinine, uric acid, and some enzymes, carbohydrates, fatty acids, pigments, and inorganic ions for eg sodium, potassium, chloride, magnesium, calcium, ammonium, sulfates, and phosphates. Lesser amounts of other compounds are present, which include hippuric acid, phosphorus, citric acid, ammonia, and uric acid. Total solids in urine add up to approx 59 grams per person. The presence of different levels of protein and sugar in the urine shows potential health concerns.
The pH of human urine is 5.5 to 7, average around 6.2. The specific gravity is 1.003 to 1.035. Significant deviations in specific gravity may be due to diet, drugs, or also because of urinary disorders.

Thus the correct answer for this solution is A 1.5%.

Note: An adult human excretes 1 to 1.5 liters of urine per day. It is light yellow in color and is slightly acidic with an odor. The composition of urine is 95% water, 2.5 % urea, 1.5% inorganic salts, and 1% other waste materials.
