Excess ki + k3fe(cn)6
TīmeklisThe excess HCl was then back titrated with 3.97 mL of 0.04012 M NaOH. ... A 0.01 molal solution of K3Fe(CN)6 freezes at 0.062C. ... (density = 1.61 g/mL) was diluted and treated with excess KI to convert hypochlorite to chloride. The liberated I2 required 22.85 mL of 0.214 M Na2S2O3 for titration. Treatment of potassium ferrocyanide with nitric acid gives H2[Fe(NO)(CN)5]. After neutralization of this intermediate with sodium carbonate, red crystals of sodium nitroprusside can be selectively crystallized. Upon treatment with chlorine gas, potassium ferrocyanide converts to potassium ferricyanide: 2 K4[Fe(CN)6] + Cl2 → 2 K3[Fe(CN)6] + 2 KCl
