Sodium Ferrocyanide Decahydrate

The boiling point of sodium ferrocyanide decahydrate is not a well-defined value since this compound tends to decompose before reaching its boiling point. However, it can be estimated to be around 100-110°C based on the boiling points of similar compounds and taking into account the fact that water molecules in the decahydrate structure lower the effective boiling point of the compound. It's worth noting that the decomposition temperature of sodium ferrocyanide decahydrate is also affected by factors such as pressure, heating rate, and impurities in the sample.

The structure of sodium ferrocyanide decahydrate is a complex ion consisting of a central iron atom coordinated to six cyanide (CN) ligands and one water molecule in an octahedral geometry. The ferrocyanide ion, Fe(CN)6^4-, carries a negative charge and is stabilized by the positively charged sodium ion (Na+) to form the compound Na4Fe(CN)6•10H2O. The decahydrate crystal structure features intermolecular hydrogen bonding between the water molecules and coordination of the sodium ions to the ferrocyanide complex.

Sodium ferrocyanide decahydrate is a compound that is commonly used as an anticaking agent, a food additive, and in the production of pigments and dyes. It is also used in the pharmaceutical industry as a stabilizing agent for certain medications. Additionally, it has applications in the electroplating industry as a source of cyanide ion. However, due to its toxicity, this compound should be handled with care and under appropriate safety conditions.

Sodium ferrocyanide decahydrate is a chemical compound that can pose several hazards if handled improperly. It is classified as a hazardous substance by the US Environmental Protection Agency (EPA) and the European Chemicals Agency (ECHA).

In addition to these acute hazards, sodium ferrocyanide decahydrate has the potential to cause chronic health effects if exposure is prolonged or repeated over time. Long-term exposure to the compound may cause damage to the kidneys, liver, and central nervous system.

To minimize the risks associated with handling sodium ferrocyanide decahydrate, appropriate personal protective equipment (PPE) should be worn when working with the substance. This may include gloves, goggles, and a respirator. Good ventilation should also be maintained in the work area to prevent the accumulation of airborne dust or vapors.

Proper storage and disposal procedures should also be followed to reduce the risk of accidental exposure. Sodium ferrocyanide decahydrate should be stored in a cool, dry place away from incompatible materials, such as strong oxidizing agents or acids. When disposing of the compound, it should be done in accordance with local regulations and guidelines.

Sodium ferrocyanide decahydrate, Na4[Fe(CN)6]·10H2O, is synthesized by reacting ferrous sulfate heptahydrate (FeSO4·7H2O), sodium cyanide (NaCN), and calcium hydroxide [Ca(OH)2] in water. The reaction forms a precipitate of ferrous hydroxide [Fe(OH)2], which reacts with the cyanide ions to form ferrocyanide [Fe(CN)6]4-. Sodium ions then replace the calcium ions in the solution to form the final product, sodium ferrocyanide decahydrate. The resulting compound can be isolated by filtration, washed with water, and dried. It is important to handle sodium cyanide with extreme caution due to its toxic nature.

Sodium ferrocyanide is a chemical compound with low toxicity. It is considered relatively safe for human consumption and has been used as a food additive (E535) in some countries. However, care should still be taken when handling large amounts of sodium ferrocyanide as it can irritate the skin and eyes. Inhaling fine particles of the compound may also cause respiratory irritation.

In case of ingestion, emergency medical attention should be sought immediately. Although rare, high doses of sodium ferrocyanide can lead to cyanide poisoning, which can cause symptoms such as nausea, vomiting, headache, confusion, and seizures. Cyanide poisoning can be life-threatening and requires immediate treatment with antidotes such as hydroxocobalamin or sodium thiosulfate.

Overall, while sodium ferrocyanide has low toxicity, it should still be handled with care and kept out of reach of children. Ingestion of large amounts of the compound can lead to serious health complications and requires prompt medical attention.

Sodium ferrocyanide is generally recognized as safe for consumption in small quantities and has low toxicity. However, ingestion of large amounts may cause gastrointestinal irritation, nausea, vomiting, and diarrhea. In rare cases, it may lead to metabolic acidosis, convulsions, hypotension, and cardiac arrhythmias. Sodium ferrocyanide can also cause skin and eye irritation upon contact. It is important to handle this compound with care and follow proper safety procedures to prevent any adverse effects.

11. Toxicological information

Sodium ferrocyanide, also known as sodium hexacyanoferrate (II), is a coordination compound with the chemical formula Na4[Fe(CN)6]. It is a yellow crystalline solid that is soluble in water and commonly used as an anti-caking agent in table salt.

Vinegar, on the other hand, is a dilute solution of acetic acid. It is typically made by fermenting ethanol with acetic acid bacteria, which convert the alcohol into acetic acid. Vinegar is commonly used as a condiment and preservative in cooking.

When sodium ferrocyanide is mixed with vinegar, a reaction occurs. The acetic acid in the vinegar reacts with the iron in sodium ferrocyanide to form iron acetate and hydrogen cyanide gas (HCN). The hydrogen cyanide gas is highly toxic and can be lethal if inhaled in large quantities.

Therefore, it is important to handle sodium ferrocyanide and vinegar with care and avoid mixing them together. In addition, proper safety precautions should be taken when working with potentially hazardous chemicals.

The chemical formula for sodium ferrocyanide decahydrate is Na4Fe(CN)6•10H2O. This indicates that each unit of the compound contains 4 sodium (Na+) ions, 1 iron (Fe3+) ion, 6 cyanide (CN-) ions, and 10 water (H2O) molecules. The "decahydrate" part of the name means that there are ten water molecules associated with each unit of the compound.

The molecular weight of sodium ferrocyanide decahydrate can be calculated by adding the atomic weights of all the atoms in its chemical formula, which is Na4Fe(CN)6·10H2O.

The atomic weight of sodium (Na) is 22.99 g/mol, iron (Fe) is 55.85 g/mol, carbon (C) is 12.01 g/mol, nitrogen (N) is 14.01 g/mol, and oxygen (O) is 16.00 g/mol. The molecular weight of water (H2O) is 18.02 g/mol.

Therefore, the molecular weight of sodium ferrocyanide decahydrate can be calculated as follows:

[(4 x 22.99) + 55.85 + (6 x 12.01) + (6 x 14.01) + (10 x (2 x 1.01 + 16.00))] + (10 x 18.02)

= 839.96 g/mol

Thus, the molecular weight of sodium ferrocyanide decahydrate is 839.96 g/mol.
