BOD- 5 represents 5 days biochemical oxygen demand at a temperature of...
BOD)5 is generally reported at 20oC.
(BOD)5 at 20o C is given by:
BOD5=Lo(1−10−kdt)
Lo = ultimate BOD
KD = Deoxygenation constant

Explanation:
BOD- 5:
- BOD-5 represents the 5 days biochemical oxygen demand, which is a measure of the amount of dissolved oxygen consumed by bacteria while decomposing organic matter in water.
Temperature:
- The BOD-5 test is typically conducted at a temperature of 20°C, which is considered ideal for the growth of bacteria responsible for decomposing organic matter in water.
Importance of Temperature:
- Temperature plays a crucial role in the BOD-5 test as it affects the rate of bacterial decomposition.
- Higher temperatures can accelerate the decomposition process, leading to a higher oxygen demand, while lower temperatures can slow down the process.
Significance of 20°C:
- 20°C is commonly used as the standard temperature for conducting BOD-5 tests because it is considered optimal for bacterial activity and provides consistent and reliable results.
Other Temperatures:
- Conducting the BOD-5 test at temperatures other than 20°C can lead to inaccurate results, as the rate of decomposition may vary significantly.
Therefore, option 'B' (20°C) is the correct temperature for conducting a BOD-5 test to accurately measure the biochemical oxygen demand in water.
