Drabkin's Solution is a mixture of potassium cyanide and potassium ferricyanide. What this solution does is hemolysis red blood cells and then hemoglobin is released.

1 answer


Potassium ferricyanide cannot be used as an internal indicator because it is an external indicator that does not change color in response to pH changes in a solution. Internal indicators are usually weak organic acids or bases that change color due to ionization changes as the pH of the solution shifts.

Potassium ferricyanide is less poisonous than potassium cyanide because it does not release cyanide ions in the body. Cyanide ions inhibit enzymes involved in cellular respiration, leading to cellular suffocation and toxicity. Potassium ferricyanide, on the other hand, is mostly harmless upon ingestion and is commonly used in non-toxic applications like photography and blueprinting.

If you want to calculate the concentration of haemoglobin, you need to convert haemoglobin into cyanmethaemoglobin, because cyanmethaemoglobin can be measured colourimetrically.

You need

- whole blood

- EDTA , and

- Drabkin's reagent.

As Haemoglobin reacts with potassium ferricyanide (in the Drabkin's reagent), haemoglobin will convert into methaemoglobin.

Methaemoglobin will react with potassium cyanide (also in the Drabkin's reagent), and you will get cyanmethaemoglobin.

-----------------------------------------------------------------------------------------------------------

Hb + potassium ferricyanide → methaemoglobin

Methaemoglobin + potassium cyanide →cyanmethaemoglobin

----------------------------------------------------------------------------------------------------------

Cyanmethaemoglobin can be measured by using a spectrometer (absorbance at 540 nm.).

Using the equation, it will give you the concentration of Haemoglobin.

----------------------------------------------------------------------------------------------------------

Hb (g/dL) = Abs. of test sample / abs. of standard x concentration of standard.

----------------------------------------------------------------------------------------------------------

(The concentration is directly proportional to the absorbance)

The valency of ferricyanide is -3. It contains one iron (III) cation with a valency of +3 and one cyanide anion with a valency of -1.

1 answer


Cyanmethemoglobin method is used to measure hemoglobin concentration in blood. In this procedure, blood sample is mixed with a solution containing potassium ferricyanide and potassium cyanide which converts hemoglobin to cyanmethemoglobin. The absorbance of cyanmethemoglobin is then measured spectrophotometrically to determine hemoglobin concentration.

ok because ammonia us too weak a ligand to replace cyanide

1 answer


The molar mass of K3Fe(CN)6 is calculated as follows:

1 potassium atom (K) = 39.10 g/mol 1 iron atom (Fe) = 55.85 g/mol 6 cyanide ions (CN) = 6 x 26.02 g/mol Adding these masses together gives the molar mass of K3Fe(CN)6 as 422.24 g/mol.
