"WebPresumably yes, considering the densities of Na (0.968 g/mL) and THF (0.8892 g/mL) sodium shouldn't float on THF. Cutting up the Na is the right way to do it, that the Na should melt is strange though, the m.p. of sodium is above the b.p. of THF... Maybe it stuck to the glass, that might explain why it would melt. Gloominati • 11 yr. ago " - Floatin' chemistry
