Chloric Acid and Chlorates

Abstract

Chlorates are salts of chloric acid [7790-93-4], HClO 3 . 1.1. Physical Properties. Aqueous chloric acid is a clear, colorless solution stable when cold up to ca 40 wt% (1). Upon heating, chlorine [7782-50-5], Cl 2 , and chlorine dioxide [10049-04-4], ClO 2 , may evolve.

The Role of Titanium Dioxide (TiO2) in the Production of Perchlorate (ClO4–) from Chlorite (ClO2–) and Chlorate (ClO3–) on Earth and Mars

“…Similarly, in a previous study where gaseous intermediates from evaporating brine under Mars condition were collected with a water trap, Cl – , ClO 3 – , and ClO 4 – were all present in the trap whereas no ClO 2 – or ClO – was detected . This indicates that chlorine dioxide (ClO 2 ) is not likely the only gaseous intermediate produced, as the thermal decomposition products of ClO 2 are ClO 2 – and ClO 3 – . The formation of gaseous intermediates also made it difficult to evaluate the effect of water on ClO 4 – formation.…”

“…34 This indicates that chlorine dioxide (ClO 2 ) is not likely the only gaseous intermediate produced, as the thermal decomposition products of ClO 2 are ClO 2 − and ClO 3 − . 42 The formation of gaseous intermediates also made it difficult to evaluate the effect of water on ClO 4 − formation. There is no way to estimate the amount of gaseous intermediates removed from the chamber by the vacuum pump in the current setup and thus the amount of ClO 4…”
