Question

A common test for liver function involves sprinkling sulfur powder onto a sample of urine (mostly water with dissolved bodily waste). Sulfur powder sprinkled on a sample from an Individual with impaired liver function will sink because the urine contains a high level of bile salts, while the sulfur powder sprinkled on normal urine samples will float.

Answer 1

Bile salts decrease the surface tension of the urine sample, that’s why the sulfur will sink in a sample from an individual with impaired liver function since it contains high levels of bile salts.

Answer 2

Bile salts caused the sulfur powder to sink because bile salts decrease the surface tension of the urine sample.

Liver function test are test procedures that are used to diagnose and monitor liver disease or damage.

When the liver is malfunctioning, such as in cases of hepatitis and cirrhosis, high level of bile salts are present in the urine. This is as a result of high serum bilirubin.

One of the fastest methods to carry out a test for liver function is sprinkling sulfur powder onto a sample of urine.

Surface tension is the quality displayed by water that enables substances of greater density float on it.

The bile salts is able to decrease the surface tension of the urine sample causing the sulfur powder to sink.
