Question

The reaction of cyanide with thiosulfate has prepared the thiocyanate ion which, when in acidic solution, bonds to the iron ions in iron(III) nitrate to form a deep red solution. Describe the resulting two-step procedure, including all reagents.

Step 1) Add [thiosulfate compound, thiosulfate and iron(III) nitrate, acid and iron(III) nitrate, iron(III) nitrate, thiosulfate compound and acid, acid] to the cyanide sample.

Step 2) Add [thiosulfate compound and acid, acid and iron(III) nitrate, acid, thiosulfate compound, thiosulfate and iron(III) nitrate, iron(III) nitrate] to the sample.

Explanation / Answer

Step 1) Add [thiosulfate compound, ] to the cyanide sample.

Step 2) Add [ acid and iron(III) nitrate, ] to the sample.

Cyanide + thiosulfate = thiocyanate

thiocyanate + iron (III) nitrate + acid = deep red solution
