Explanation:
Amphoteric compounds is an ion or molecule which can react both as an acid as well as the base. It is also used as a disinfectant that is used manually in soak or spray applications. However, it is user-friendly. It ionizes to produce cations, anions, or zwitterions.
Question 6
Which of the following disrupts the microorganisms via osmotic shock?
A. Amphoterics
B. Biguanides
C. Peracetic acid
D. Chlorine
View Answer
Answer: Option A
Explanation:
Biguanides are the sterilents which disrupt the microorganisms via osmotic shock. It is a non-oxidising cationic polymer and is typically used in a concentration of 600 mg/l. However, below the pH of 3, biguanides are not effective.
Question 7

Question 8
Which of the following is the longest part of the CiP cycle?
A. Drain
B. Detergent recirculation
C. Scavenge water rinse
D. Pre-rinse to drain
View Answer
Answer: Option B
Explanation:
The detergent recirculation is the longest part of the CiP cycle. It is for about 30 – 60 minutes. The efficacy is determined by detergent strength, time, temperature, and flow. The strength of the detergent requires to be assured to account for contact with carbon-dioxide in alkaline recovery systems.
