Determination of chloride in sulphuric acid by potentiometric mercurometric titration.
The chloride content of concentrated sulphuric acid is determined by mercurometric titration in 80% v/v methanol medium, with a mercury pool as indicator electrode. The method is simple, fast, accurate and reasonably sensitive (limit of detection 4.5 mug/ml), and suitable for routine application.
