A: Whether you can deduct IRA contributions on your tax return depends on the type of IRA you have, your participation in an employer-sponsored retirement plan, and your income. Roth IRA contributions are never tax deductible; you must pay taxes on Roth IRA funds before you place them in your account.
Sodium borohydride. Sodium borohydride, also known as sodium tetrahydridoborate and sodium tetrahydroborate, is an inorganic compound with the formula NaBH4. This white solid, usually encountered as a powder, is a versatile reducing agent that finds wide application in chemistry, both in the laboratory and on a technical scale.
It can be purified by recrystallization from warm (50 Â°C) diglyme. Sodium borohydride is soluble in protic solvents such as water and lower alcohols; it will also react with these solvents to produce H2; however, these reactions are fairly slow. Complete decomposition in excess methanol can take nearly 90 min at 20 Â°C.
