SODIUM FORMATE
Sodium formate (NaCHO2) is the sodium salt of formic acid. It appears as a white, crystalline solid with a slight odor. This compound
is highly soluble in water, with solubility increasing significantly with temperature, making it useful in various industrial applications.
Sodium formate has a molecular weight of 68.01 g/mol and melts at around 253°C, decomposing at higher temperatures to yield
hydrogen gas and sodium oxalate. In aqueous solutions, it acts as a weak base due to the hydrolysis of the formate ion, which can
slightly increase the pH of the solution. It is used in several industries, including as a buffering agent in dyeing and printing textiles,
as a de-icing agent for airport runways, and in the leather tanning process. Additionally, sodium formate can be employed as a food
additive and in the manufacturing of other chemicals. Its relatively low toxicity makes it a safer alternative to some other de-icing
chemicals and industrial agents.

Sodium formate, the sodium salt of formic acid, has several industrial and commercial applications. It is commonly used in the
leather industry for the tanning process, where it helps in stabilizing the chromium used in the tanning process. In the textile industry,
sodium formate serves as a buffering agent and a reducing agent, aiding in dyeing and printing processes. It is also used in the
production of formic acid, a preservative and antibacterial agent.In the field of de-icing and anti-icing, sodium formate is utilized
for airport runways and roads due to its effectiveness and lower environmental impact compared to traditional salts. Additionally,
it finds application in the oil and gas industry as a drilling and stabilizing agent in drilling fluids.
