Basic because when sodium borohydride is placed in water, the sodium ion and the borohydride ion split, borohydride abstracts a proton (in the form of H+) from a water molecule.

Yes

Sodium borohydride is a common laboratory chemical used as a reducing agent. Its Material Safety Data Sheet (MSDS) would provide information on its physical and chemical properties, health hazards, safety precautions, and first-aid measures in case of exposure. You can usually find the MSDS for sodium borohydride on the website of the manufacturer or supplier.
