The stated purpose of this paper is to provide a simple and quick method to assemble pH electrodes using readily available materials. The present assembled electrodes are comparable with commercial pH electrodes, with accuracy for pH determination in the range 2-12. Furthermore, the constructed simple pH electrodes exhibit a fast and stable response with a relatively wide linear range, meaning that these electrodes offer the promise of potential utilization in experiments. The inexpensive assembly and use of these pH glass membrane electrodes lends itself to introductory electrochemistry lab experiments at only a fraction of the cost of commercial electrodes. Under the guidance of instructors, students could make and test their own electrodes for chemical experiments. This might be helpful for students to gain a deeper understanding of the fundamentals of electrochemistry, such as the structure of ion-selective electrodes, the Nernst equation, etc.
