Title: Stability of NaBH[sub]4[/sub] in NaOH (aq) ?
Post by: El_Zorro on September 29, 2002, 11:44:00 PM
How long can a stock solution of NaBH4 and NaOH sit at RT before the NaBH4 decomposes?

Is water the solvent?

Title: Depends on pH.

The rate of decomposition depends on the pH but if the solution is strongly basic it can be quite stable. Basic aqueous NaBH4 solutions are sold comercially.

So about a 3M NaOH solution would keep it stable indefinately, or close to it?

Rhod- are you sure that link is correct?  I don't see how whether or not scottydog wears a rubber or not can be helpful in storing NaBH4. 8)
