aqueous NaBH4?

[FriendlyFinger]

When a synth calls for "an aqueous solution of NaBH₄", does that mean NaBH₄ + water, or NaBH₄ + water + NaOH.

Thanks,

In most procedures I've seen using aqueous borohydride they simply dissolve NaBH₄ in water. If nothing in the reaction mixture is overly sensitive towards hydroxide ions there should be no problems adding the small amounts of NaOH necessary to stablize the borohydride.
