Chapter 19, Problem 20RQ
What naturally occurring element has been contaminating the water supply of Bangladesh?
Expert Solution & Answer
To determine
The naturally occurring element in Bangladesh that has been contaminating the water supply
Answer to Problem 20RQ
Arsenic is the naturally occurring element in Bangladesh that has been contaminating the water supply.
Explanation of Solution
In Bangladesh, for drinking water purpose very deep wells are made in order to avoid the pathogens present in surface water. But the water obtained from these deep wells is found to be highly contaminated with arsenic occurring naturally in the earth’s crust. The arsenic contaminated water can cause arsenic poisoning by forming skin lesions and a high risk of having cancer.
Conclusion:
Therefore, Arsenic is the naturally occurring element contaminating the deep well water in Bangladesh.

- Imagine you are out for a stroll on a sunny day when you encounter a lake. Unpolarized light from the sun is reflected off the lake into your eyes. However, you notice when you put on your vertically polarized sunglasses, the light reflected off the lake no longer reaches your eyes. What is the angle between the unpolarized light and the surface of the water, in degrees, measured from the horizontal? You may assume the index of refraction of air is nair=1 and the index of refraction of water is nwater=1.33 . Round your answer to three significant figures.
