Sodium Borohydride Formula and Molar Mass

The chemical formula for Sodium Borohydride is NaBH4, indicating its composition as sodium (Na), boron (B), and hydrogen (H). This compound boasts an estimated 37.83 g/mol molar mass that makes it effective in various chemical reactions.

Sodium Borohydride Uses

It is primarily used as a reducing agent, meaning it donates hydride ions (H-) to chemical reactions. This makes it a valuable compound in several applications, including:
1. Chemical Reduction: It is commonly used to reduce aldehydes and ketones to their respective alcohols. It’s a milder alternative to other reducing agents like lithium aluminum hydride (LiAlH4), which can be more reactive and potentially lead to side reactions.
2. Organic Synthesis: It finds use in various organic synthesis reactions to achieve specific reductions in complex molecules.
3. Textile Industry: Sodium Borohydride is used in the reduction of dyes and other chemical compounds in the textile industry, aiding in color fixing and enhancing colorfastness.
4. Pulp and Paper Industry: It’s utilized to remove residual chlorine in the bleaching of wood pulp in the paper industry.
5. Fuel Cells: It can be used as a hydrogen storage material in fuel cells, releasing hydrogen when needed for energy generation.
6. Metal Recovery: It’s used in the recovery of precious metals from solutions, as it can reduce metal ions to their elemental forms.
7. Photography: In the past, it was used in photographic processes as a reducing agent to develop photographic prints and films.

Sodium Borohydride Water Reaction

One of the unique properties of Sodium Borohydride is its reaction with water (H2O). When it reacts with H2O it undergoes hydrolysis to release hydrogen gas (H2) as well as sodium hydroxide (NaOH).
NaBH4 + 2H2O = NaBO2 + 4H2
In this reaction, sodium borohydride acts as a reducing agent by providing electrons to water molecules to form hydrogen gas and sodium hydroxide as the final product – remaining in solution as an inert substance.

For comprehensive chemical information, I recommend referring to PubChem for details about Sodium Borohydride.

Safety Considerations:

Sodium Borohydride CAS 16940-66-2 is generally considered to be safe when handled properly, but it is a reducing agent and can react vigorously with water, acids, and oxidizing agents. It can release flammable hydrogen gas upon contact with water. Therefore, it should be handled with caution, preferably under controlled conditions, and proper personal protective equipment (PPE) should be worn.
