To determine the correct matches from List I (Name of Emulsifier) with List II (Remark), we need to understand each emulsifier and its type of surfactant or emulsifying agent.
- Triethanolamine oleate: It is known as a surface-active agent and typically functions as an anionic surfactant due to its oleate component. Therefore, it corresponds to III. Surface-active agent (anionic).
- N-ethyl N-ethylmorpholinium ethosulfate (Atlas G-263): This is a cationic surfactant because it is based on a quaternary ammonium compound. Therefore, it corresponds to V. Surface active agent (cationic).
- Polyoxyethylene sorbitan monooleate (Atlas Tween 80): This compound is often used as a non-ionic surfactant. Therefore, it corresponds to I. Surface-active agent (non-ionic).
- Gelatin: Gelatin is a protein and acts as a hydrophilic colloid, commonly used as an emulsifier in pharmaceuticals. Therefore, it corresponds to II. Hydrophilic colloid.
Based on these understandings, the correct matches are:
- A - III: Triethanolamine oleate is a Surface-active agent (anionic).
- B - V: N-ethyl N-ethylmorpholinium ethosulfate (Atlas G-263) is a Surface active agent (cationic).
- C - I: Polyoxyethylene sorbitan monooleate (Atlas Tween 80) is a Surface-active agent (non-ionic).
- D - II: Gelatin is a Hydrophilic colloid.
Therefore, the correct option is A-III, B-V, C-I, D-II.
