Suspended solids in water can increase the haziness of the water. Which of the following represents the measurement of haziness of water?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Turbidity.
Turbidity is the measurement used to represent the haziness or cloudiness of water caused by suspended solids such as silt, clay, organic matter, and microorganisms. These particles scatter and absorb light, reducing water clarity and making it appear murky. High turbidity indicates poor water quality and can harbor harmful pathogens, affecting aquatic life and human health. It is measured using instruments called turbidimeters, which assess the amount of light scattered by suspended particles. Controlling turbidity is important for safe drinking water, effective water treatment, and maintaining healthy aquatic ecosystems. Turbidity is a key indicator in water quality assessment.
Other options :
-
Salinity: Measures the concentration of dissolved salts in water, not its haziness.
-
Solubility: Refers to how much of a substance can dissolve in water.
-
Viscosity: Measures the resistance of water to flow, unrelated to cloudiness.
