Use shorter precipitate time as faster hydrolysis, identify silver-halide colour and separate the effects of halogen identity from primary, secondary or tertiary structure.

How this is tested

  • Use reciprocal precipitate time to compare hydrolysis rates in aqueous ethanol.
  • Identify AgCl, AgBr or AgI from white, cream or yellow precipitate formation.
  • Compare structural class and C–X strength as separate reasons for different rates.
