No, if you use water, you will have decomposition of sodium borohydride. You have to add sodium hydroxide to stabilize the solution. See International Journal of Hydrogen Energy 2012 p3313-3318

Decomposition of sodium borohydride starts when it reacts with water molecules. Use of base like NaOH can prevent its decomposition. I suggest to use NaBH4 powder instead of aqueous solution.

Hi Sumisha A. , As you know, to keep the solution of NaBH4 stable during storage, you need to use water at a basic range (See attached Figure to explore the stability time of NaBH4 at different pH values). However, at room temperature, 1.0 N NaOH solution was considered appropriate to meet the stability requirements for the borohydride solutions during the long-term storage with a degree of hydrolysis equal to 0.01% NaBH4/h (see ArticleStability of alkaline aqueous solutions of sodium borohydride )
For preparing a stable solution of NaBH4, you need to perform the following steps: 1- prepare 1.0 N NaOH solution. 2- cool the solution with an ice-water bath. 3- add the dry granulated NaBH4 to the NaOH solution under stirring conditions until a homogeneous mixture is formed.
You can use this solution as a stock for further uses.

It's a very common commercial reagent. I think you are using water as solvent in your reaction. You can prepare sodium borohydride solution using water also.

Sodium borohydride is soluble in water, but it reacts with water. When dissolved in water, hydrogen gas is formed as a reaction by-product. Hydrogen gas is extremely flammable. how do you prepare it with soft method????

Try prepare with ice cold water because it could react violently at room temperature if prepared with warm water
