General description

Crystals of potassium chlorate belong to the monoclinic crystal system. On heating above 400°C, it degrades to give potassium chloride and potassium perchlorate. It has strong oxidizing properties. On exposure to X-rays, oxygen-17 enriched KClO3 generates O3- radical, which was investigated by ESR (Electron Spin Resonance). Irradiation of potassium chlorate with X-ray causes the degradation to generate chloride, chlorite, hypochlorite and occluded oxygen. Significant quantities of dichlorine hexoxide and a trace of chlorine dioxide were also produced.

Application

Potassium chlorate may be used in the preparation of graphite oxide (GO).

Characterization of conformational transition and folding intermediates is central to the study of protein folding. We studied the effect of various alcohols (trifluoroethanol (TFE), butanol, propanol, ethanol and methanol) and salts (K(3)FeCN(6), Na(2)SO(4), KClO(4) and KCl) on the acid-induced state
