 is + 1 @.@ 92 V , beyond that for chlorine to chloride , + 1 @.@ 36 V. Consequently , cobalt ( III ) and chloride would result in the cobalt ( III ) being reduced to cobalt ( II ) . Because the reduction potential for fluorine to fluoride is so high , + 2 @.@ 87 V , cobalt ( III ) fluoride is one of the few simple stable cobalt ( III ) compounds . Cobalt ( III ) fluoride , which is used in some fluorination reactions , reacts vigorously with water .
