Full title and description

ASTM E200-23 — Standard Practice for Preparation, Standardization, and Storage of Standard and Reagent Solutions for Chemical Analysis. This practice provides recommended procedures, terminology, and detailed preparation/standardization procedures for common volumetric and reagent solutions used in routine chemical analysis and titrations.

Abstract

This standard consolidates methods for preparing, measuring, standardizing, and storing standard volumetric and reagent solutions (titrants, indicators, and other reagents). It includes temperature considerations, apparatus, concentration and mixing guidance, storage recommendations, and worked examples/precision statements for widely used solutions (e.g., NaOH, HCl, H2SO4, AgNO3, I2, Na2S2O3, KMnO4, EDTA). The document is intended to improve accuracy and reproducibility of routine chemical analyses.

Scope

This practice covers procedures for the preparation, standardization, and storage of the standard volumetric solutions and reagent testing solutions commonly used in chemical analysis, including recommended apparatus, temperature and measurement considerations, concentration ranges, mixing and storage guidance, and standardization techniques for commonly used titrants and reagents. It does not replace safety, regulatory, or SDS requirements for hazardous materials — users must apply appropriate safety practices.

Key topics and requirements

• Terminology and definitions relevant to standard and reagent solutions (standard volumetric solution, titrant, indicator solutions).
• Recommended apparatus and measurement techniques to reduce volumetric errors (pipets, flasks, balances, temperature control).
• Temperature effects and corrections for volumetric measurements.
• Preparation procedures and concentration ranges for common solutions: sodium hydroxide, hydrochloric acid, sulfuric acid, silver nitrate, ammonium thiocyanate, iodine, sodium thiosulfate, potassium permanganate, potassium dichromate, ceric sulfate, acetous perchloric acid, EDTA, standard ion solutions, and nonstandardized reagent/indicator solutions.
• Standardization/titration procedures for each reagent and suggested primary/secondary standards where applicable.
• Storage recommendations (containers, protection from light/CO2/moisture, shelf-life guidance) and labeling.
• Precision and bias statements or interlaboratory precision information where provided.

Detailed topic coverage and section organization are given in the standard’s table of contents and example procedures.

Typical use and users

Laboratories in analytical chemistry, quality control/quality assurance, environmental testing, petroleum and materials testing, academic teaching and research labs, production QC in chemical and pharmaceutical firms, and instrument calibration facilities use this practice as a reference for consistent preparation and standardization of routine reagent and volumetric solutions.
