Question

Concentration of Copper in drinking water is:
A. ${\text{5 ppm}}$
B. ${\text{3 ppm}}$
C. ${\text{0}} \cdot {\text{3 ppm}}$
D. ${\text{0}} \cdot {\text{05 ppm}}$

Answer 1

Hint: Copper is a naturally occurring element, and is needed by the human body to remain healthy. But, its concentration in the body should be under the desired level otherwise, it becomes harmful for the health.

Complete step by step answer:
- Copper is the ${\text{2}}{{\text{9}}^{{\text{th}}}}$ element of the periodic table having the symbol ${\text{Cu}}$, and comes under the coinage group metal. Like other minerals, and nutrients, Copper is also an essential intake of our body. One way of taking Copper inside the body is through the drinking water we intake. A compound of Copper called the Copper sulphate pentahydrate is added to water bodies to kill, and resist the growth of the bacteria, and algae.
-The concentration of Copper in the water is maintained by calculating the ${\text{pH}}$ of water, dissolved oxygen in that water, by checking if there are some oxidising agents or chelating agents are present or not.
-In pure water Copper forms complexes with carbonates, and hydroxide ions of water to exist in stable Copper$II$ oxidation state.
-Considering all the above factors the required concentration of Copper in drinking water is ${\text{3 ppm}}$ where ${\text{ppm}}$ is a unit of measurement called parts per million.
Hence, option (b) ${\text{3 ppm}}$ is the correct concentration of Copper in drinking water.

Note: One way of Copper intake with drinking water is to store the water in a Copper bottle. Drinking water stored in Copper bottle is most effective for an empty stomach. However, high consumption of Copper can lead to vomiting, diarrhoea, nausea, and gastric problems related to stomach.
