Question

Accepted Answer

1.5 litres. Human urine is an aqueous solution made up mostly of water, with the remaining constituents made up of urea, creatinine, dissolved ions (chloride, sodium, potassium, etc), inorganic and organic compounds or salts. An adult human on an average excretes 1 to 1.8 liters of urine per day. It is light yellow in colour, slightly acidic (pH - 6.0) with a characteristic odor. The composition of urine is 95% water, 2.5% urea and 2.5% other waste. As urea is the major excretory waste humans are considered ureotelic.
