There are 4 easy steps to find the molar mass of BH4 {-} based on its chemical formula. 1. Count The Number of Each Atom. The first step to finding the molar mass of Borohydride is to count the number of each atom present in a single molecule using the chemical formula, BH4 {-}:
Borohydride - Wikipedia
Borohydride or hydroborate is also the term used for compounds containing [BH4−nXn]−, where n is an integer from 0 to 3, for example cyanoborohydride or cyanotrihydroborate [BH3(CN)]− and triethylborohydride or triethylhydroborate [BH (CH2CH3)3]−. Borohydrides find wide use as reducing agents in organic synthesis.
Sodium borohydride - Wikipedia
Sodium borohydride, also known as sodium tetrahydridoborate and sodium tetrahydroborate, [5] is an inorganic compound with the formula Na B H 4 (sometimes written as Na [BH4]). It is a white crystalline solid, usually encountered as an aqueous basic solution.
Sodium borohydride powder, = 98.0 16940-66-2 - MilliporeSigma
Sodium borohydride (NaBH 4) is the most commonly available borohydride, synthesized by reacting methylborate with sodium hydride in mineral oil. It is employed as a precursor for producing other metal borohydrides. Various approaches for qualitative and quantitative monitoring of sodium borohydride have been explained. [1] .
