Coulometric Titration of Acid

Written by Morgan I. Introduction: This experiment is concerned with determination of the concentration of a standard solution of HCl. Coulometric titrations are performed using MicroLab FS 522 with MicroLab Model 290 sensor adaptor module to gather data regarding electric current variability. The theories underlying this variety of titration include redox reactions, current and total charge, and the techniques of coulometric measurement of electrolysis can be found in the following materials1: D.C.

Acid-Base Titrations: Standardization of NaOH and Antacid Analysis

Acid- Base Titrations By Julia Trimble Introduction: A titration is a procedure in which two solutions are introduced to form a reaction that once completed, reaches an identifiable endpoint (Murphy, 2012, p.305). During a titration, the volume of one reagent, the analyte, is predetermined while the other reagent, the titrant, is prepared in a buret and slowly introduced to the analyte solution. The completion of this reaction can be determined via observation through the use of an indicator. The […]

Titration of a Diprotic Acid Lab Steps

Objective: The purpose of this experiment is to determine an unknown diprotic acid by examining its molecular weight using titration. Procedure: (1) Dissolve 0.120 g of the unknown in 100 mL of distilled water. (2) Place the 250 mL beaker ontop of a magnetic stir plate, and suspend a pH electrode into the solution using a ring stand. (3) Fill buret to 0 mL level with sodium hydroxide, prepare computer software. (4) Wait for pH to stabilize then keep data […]
