Hypo is used in photography because it is:
  • A
    A strong reducing agent
  • B
    A strong oxidizing agent
  • C
    A strong Complexing agent
  • D
    Photo sensitive Compound
✓

Answer

  1. A strong Complexing agent

Explanation:

Hypo forms the complex [Ag(S2​O3​)2​]3− from insoluble Ag.

[Ag(S2​O3​)2​]3− is formed by treatment of Na2​S2​O3​.5H2​O with AgBr.

Therefore, Hypo is used in photography because it is a strong Complexing agent.
