Silver Salt Method
These salts break down into a metallic silver residue when heated.
The reaction is:
RCOOH + NH4OH → RCOONH4 + H2O
RCOONH4 + AgNO3 = RCOOAg + NH4 NO4
RCOOAg = 2Ag + CO2 + R-R.
- A little amount of carboxylic salt is used in this procedure, and it is treated with an excess ammonium hydroxide solution to produce the acid's ammoniacal salt.
- Extra ammonia was heated out of the solution.
- A white precipitate of the acid's silver salt is then created by treating it with ammonium nitrate salt.
- After that, the precipitate is cleaned and dried.
- The salt is then burned until an Ag residue that is silvery is produced.
- The equivalent mass of the acid can be calculated from the equivalent mass of the salt.
In order to determine the molecular weights of organic compound acids, the Silver salt method is used.
The silver salt method is used for the determination is molecular weights of which organic compound? (A) Acids (B) Bases (C) Hydrocarbons (D) Suphonic acid
For determining the molecular weights of organic compound acids, the silver salt technique is utilized. The equivalent mass of the silver salt can be calculated using the mass of the silver salt that was taken and the silver that was left over.
