Turbidity in a sample refers to what?

Turbidity in a sample refers to what?

• A. Clear liquid with no cloud
• B. Color change only
• C. Cloudiness
• D. Increased viscosity

Answer: (C)

Turbidity measures how hazy a liquid is due to particles suspended in it. Those particles scatter light, making the liquid appear cloudy, so turbidity is about cloudiness rather than color or thickness. The best description among the options is cloudiness, since turbidity specifically reflects how opaque or hazy the liquid looks because of suspended solids. Color change involves pigments or chemical reactions and isn’t the definition of turbidity, and increased viscosity is about how thick a liquid is and its flow, not how clear it is. In practice, higher turbidity indicates more suspended material and can have implications for water quality and disinfection effectiveness.
