The chlorate contained a trace of chloride. In consequence 

 of the degrees of electromotive force produced by solutions of 

 these salts being so little greater than that produced by water 

 alone, viz. 1*127 volt, it was necessary to use much stronger 

 solutions than those of the previous substances ; the ones 

 employed contained from *7 to 1*7 grains in 155 grains of 

 water.
