Product Overview

Potassium Iodate 99.5% AR (CAS No. 7758-05-6) is an iodine(V) oxyanion salt with reproducible oxidising chemistry. In acidic iodide-containing media, iodate can stoichiometrically produce iodine, making the iodate-iodide system useful in iodometric and related titrimetric procedures. Its relative chemical stability also makes potassium iodate a useful reagent for preparing oxidising solutions in conventional analytical chemistry.

The AR grade is intended for iodometric reagent preparation, redox titrimetry, analytical oxidations and laboratory quality control. The 99.5% assay suits all the laboratory activities that require higher purity and low impurity interference in the analytical system.

Typical Applications

• Preparation of iodate reagent solutions for conventional iodometric procedures.
• Generation of iodine from iodide for titrimetric determination of reducing substances.
• Potassium iodide–iodate reagent systems used in established wet-chemical analysis.
• Standardisation and verification of iodine/thiosulphate redox systems where method requirements are satisfied.
• Analytical oxidation of suitable reducing analytes.
• Laboratory QC and redox-method verification involving iodate chemistry.

Common Synonyms

• Iodic acid potassium salt
• Potassium iodate(V)
• Potassium trioxidoiodate

Storage Conditions

Keep tightly closed, dry and free from contamination by reducing agents or reactive matter capable of consuming iodate. Use clean analytical dispensing practices to preserve oxidising capacity and solution-preparation consistency.
