Question

Bromine is sometime used as a disinfectant because:

A) It raises PH
B) Combined bromine is still an effective sanitizer/ It is more stable at higher temperatures than chlorine
C) Is inexpensive
D) All of the above

Answer 1

Bromine is sometimes used as a disinfectant because it raises the pH, combined bromine is still an effective sanitizer, and it is more stable at higher temperatures than chlorine.

Step-by-step explanation:

Option D) All of the above is the correct answer. Bromine is sometimes used as a disinfectant because it raises the pH, combined bromine is still an effective sanitizer, and it is more stable at higher temperatures than chlorine. Let's break it down:

1. It raises pH: Bromine is an effective disinfectant in pool and hot tub water because it raises the pH level. This makes the water more alkaline, which inhibits the growth of bacteria and other microorganisms.
2. Combined bromine is still effective: Bromine compounds, such as bromamines, are formed when bromine combines with organic matter. These bromamines are still effective sanitizers, unlike chlorine compounds.
3. More stable at higher temperatures: Bromine is more stable than chlorine at higher temperatures, which makes it suitable for use in hot tubs and Jacuzzis.

Therefore, the correct answer is D) All of the above.
