Iron(III) thiocyanate - American Chemical Society
2024年1月22日 · Iron(III) thiocyanate [Fe(SCN) 3], aka ferric thiocyanate, is an iron salt with a striking deep red—almost black—color as a solid and a blood-red color in aqueous solution (see image). It first appeared in the chemical literature in 1884 in an article in the long-defunct Dinglers Polytechnisches Journal .
Thiocyanate - Wikipedia
Thiocyanates are salts containing the thiocyanate anion [SCN]− (also known as rhodanide or rhodanate). [SCN]− is the conjugate base of thiocyanic acid. Common salts include the colourless salts potassium thiocyanate and sodium thiocyanate. Mercury …

2020年8月15日 · The local additions of either ferric ions or thiocyanate ions will each provide local color intensities by shifting the equilibrium. Iron nitrate shifts the above equation to the right, and so too does potassium thiocyanate. By complexing the available Fe 3+ ions in the solution, NaHPO 4 shift the reaction to the left. Hazards:

Iron thiocyanate is a chemical compound formed when iron (Fe) reacts with thiocyanate ions (SCN-) in solution. It forms a reddish-colored complex known as iron (III) thiocyanate. Complex Ion Formation: Complex ion formation occurs when two or more molecules or ions combine to form a larger structure held together by coordinate bonds.
Iron (III) Thiocyanate Equilibrium – HSC Chemistry - Science Ready
The formation of iron (III) thiocyanate complex ion is an exothermic reaction. This means the forward reaction is favoured at a low temperature. Figure: effect of temperature on the dynamic equilibrium of iron thiocyanate solution. When the solution is placed in ice-cold water, more iron thiocyanate ion is formed.
MAKE SURE TO USE THE CORRECT CONCENTRATIONS! Set up 7 beakers in a row. Add 75 mL 0.001 M Fe(NO3)3 AND 75 mL 0.001 M KSCN to the last five beakers, producing the orange colored species FeSCN2+. Cover with petri dishes labeled FeSCN2+. The solution should look like Tang or Kool-Aid. If it is dark or brown, you used the wrong concentration.
