Institutional Use:
Adopted by universities and government labs involved in chemical education, analytical testing, and inorganic chemistry research.

FAQs

1. What is yellow ammonium sulphide used for?
   It is used in qualitative chemical analysis for identifying certain metal ions by precipitate formation.

2. Is it the same as colorless ammonium sulphide?
   No, yellow ammonium sulphide contains polysulphides and has different reactivity and shelf stability.

3. Can it be used in titration?
   No, it is not typically used in titration but rather in spot tests and precipitation reactions.

4. How should it be stored?
   Store in a tightly closed container in a cool, ventilated area away from light and air exposure.

5. Is it suitable for undergraduate chemistry labs?
   Yes, it’s widely used in academic practicals for salt analysis demonstrations.
