Measurement of water diffusivity in aqueous lithium bromide solution.

摘要

The bulb apparatus developed was found to produce reliable data for measuring diffusivity for short duration. Diffusivity of water in aq. LiBr solution was found to increase from 13.2(times)10(sup (minus)10) to 16.7(times)10(sup (minus)10)m(sup 2)/s for concentration change from 0.5 to 4M and then decrease to a steady value of (approximately)6.5(times)10(sup (minus)10)m(sup 2)/s from 8 to 11 M.
