| Abstract: | Iodimetric analysis performed in acetic acid medium in the presence of host tin and antimony ions is presented.The tin ions and antimony ions are masked with tartaric acid using hydrochloric acid as medium and formed into stable complex compound.The results are accurate with simplified procedures,improved effectiveness and reduced reagent cost.This method has been employed with good results for determining copper in tin-based bearing alloy,Babbitt alloy and crude copper containing tin and antimony. |
