The equivalent weight of ammonium thiocyanate is calculated by dividing the molecular weight by the total positive or negative charge of the compound. For ammonium thiocyanate (NH4SCN), the molecular weight is approximately 76.12 g/mol and the total positive charge is +1 (from the ammonium ion), so the equivalent weight is 76.12 g/mol.
The formula for ammonium thiocyanate is NH4SCN.
Ammonium Chloride
The reaction between ammonium thiocyanate (NH4SCN) and water is as follows: NH4SCN + H2O → NH4+ + SCN- + H2S. This reaction forms ammonium ion (NH4+), thiocyanate ion (SCN-), and hydrogen sulfide gas (H2S).
The chemical formula for ammonium thiocyanate is NH4SCN.
The equivalent weight of ferric ammonium sulfate is 392.14 g/mol.
The formula for ammonium thiocyanate is NH4SCN.

Ammonium thiocyanate is used as an indicator in the iodometry of copper because it forms a red complex with copper ions. By adding ammonium thiocyanate to the copper solution, the color change from white to red indicates the end point of the titration, allowing for the determination of copper concentration.
Very simply 1g of ammonium thiocyanate and 100g (100ml) of water!
This is a very complicated question and the answer would have to be figured out by experiment. Commiserations.
Ammonium thiocyanate is added in the titration of sodium thiosulphate with copper to detect the end point of the reaction. When all the thiosulfate ions react with copper ions, excess copper ions will react with ammonium thiocyanate forming a reddish-brown complex. This color change indicates that all the thiosulfate has reacted and the titration is complete.
When ammonium dichromate and mercury thiocyanate are combined, a chemical reaction called a decomposition reaction occurs. This reaction produces a visually striking effect known as the "Pharaoh's serpent" or "Pharaoh's snake," where a dark, coiling mass of solid material is formed.
Adding ammonium thiocyanate prior to the end point in a titration helps to detect the endpoint as it forms a red color complex with the metal ion being titrated. This complex formation signals the approach of the endpoint and allows for a more precise determination of the equivalence point in the titration.
