Zorluk: OrtaChemistry in Daily Life and Industrial Applications

Consider the following statements regarding chemical compounds commonly used as therapeutic agents and food additives in daily life:

1. A 0.2%0.2\% aqueous solution of phenol acts as an antiseptic, whereas its 1.0%1.0\% solution functions as a disinfectant.
2. Aspartame is widely used as an artificial sweetener in baked confectionery due to its high thermal stability at baking temperatures.
3. Bithionol is compounded into toilet soaps to impart antiseptic and antimicrobial properties.

Which of the statements given above is/are correct?

  1. 1 and 3 onlyCevap
  2. B
    1 and 2 only
  3. C
    2 and 3 only
  4. D
    1, 2 and 3

Cevap

1 and 3 only
The combination stating '1 and 3 only' is correct because dilute phenol (0.2%0.2\%) serves as an antiseptic while 1.0%1.0\% phenol functions as a disinfectant, and bithionol is the standard chemical additive used to confer antiseptic qualities to cleansing soaps. Aspartame decomposes at high baking temperatures and is therefore unusable in cooked confectionery.

Adım Adım Çözüm

1
Analyze statement 1 regarding the antiseptic versus disinfectant properties of phenol
Statement 1 is valid
Phenol behaves differentially based on concentration: a dilute 0.2%0.2\% solution is safe for application on living tissues (antiseptic), while a stronger 1.0%1.0\% solution is toxic to living tissues and used for inanimate surfaces (disinfectant).
2
Analyze statement 2 regarding the thermal behavior and practical applications of aspartame
Statement 2 is invalid
Aspartame (the methyl ester of aspartic acid/phenylalanine dipeptide) is roughly 100 times sweeter than cane sugar but is thermolabile; it decomposes at cooking and baking temperatures, restricting its application strictly to cold foods and soft drinks.
3
Analyze statement 3 regarding the role of bithionol in personal care products
Statement 3 is valid
Bithionol (bithional) is a halogenated phenolic compound systematically added to toilet soaps to impart antiseptic properties and curb the bacterial degradation of sweat.
