Development of small-scale titration set as a tool for teaching analytical chemistry

Abstract

In this work, we are reported the experimental research which aimed to development of a small scale titration set (SSTS) for laboratory in chemistry classroom and study the effective of developed SSTS. SSTS is simple to created using a simple, low-cost materials and available in local area, consist of a 20 ml plastic syringe with a rubber tip which used as a buret, a 5 mL plastic cup which used as Erlenmeyer flask and a plastic bottle was created as a stand. The results obtained from the developed titration set were slightly difference from standard titration set. The acceptable value of % relative error was obtained from using SSTS is 8%. The analytical assay through the SSTS is simple, to us less amount of reagents and low-cost. It is suitable for teachers to us this SSTS for teaching titration in chemistry classroom. The SSTS can be replaced the standard titration set that it is expensive materials.
