Dielectric constants of aqueous solutions of dextrose and sucrose

Abstract

Th e dielectric constants of aqueous solut ions of dextrose and of sucrose prepared from N BS Standard SampJes were d etermin ed a t 20,25, a nd 30 C fo r cOJlcentra t ions upto 50 and 60 p erce nt by we igh t, respective ly. A bri dge method wa s used , a nd t he so urceE of errol' involved are con sidere d. Th e r esu lts, relative to a se lected valu e for water, ar e considered t o be accurate to 0.05 percent or better and are expr essed in term s of an e mp iri cal e quation for the pu rposes of in terpola t ion.
