Simple and Low-Cost Setup for Measurement of the Density of a Liquid
Noei, Nima; Imani, Iman Mohammadi; Wilson, Lee D.; Azizian, Saeid
Journal of Chemical Education, v96 n1 p175-179 Jan 2019
A low-cost and simple setup to measure the densities of liquids is introduced herein. The results and reliability of this setup were evaluated for pure liquids, water-ethanol binary mixtures, and aqueous NaCl solutions. The constructed densitometer provided density values with acceptable relative errors (less than ±3.0%), which were compared to estimates of density from the literature. The favorable agreement is surprising for such a simple and low-cost setup. The facile design lends itself to use in diverse teaching environments to reinforce the ubiquitous concept of density at the secondary-school level and for undergraduate physical-chemistry teaching laboratories.
