Question

1)Tetrahydrofuran (THF), a cyclic ether commonly used as a solvent in both organic and inorganic chemistry, is often dried by stirring over elemental sodium overnight, followed by distillation under nitrogen or argon. Suggest two possible hazards of this procedure, and steps you might take to minimize them.

2)Using hard/soft acid-base theory, predict which of the following metals are likely to give especially toxic salts (of course, most laboratory compounds are toxic in sufficient quantities): Fe, Cd, Co, Ti, Zr, Zn, Tl, Pb.

3)Do the relative toxicities of HF, HCl, HBr, and HI track with their relative acidities in water? Explain.
