How long can a stock solution of NaBH4 and NaOH sit at RT before the NaBH4 decomposes?

Is water the solvent?

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)

*hrm* :-[  - anyway, I ment to link to another post which said that NaBH4 in aqueous NaOH is sold commercially...

That's cool, I've been wondering whether or not Scotty wraps his weiner. ;)
