AMMONIUM IODATE. 



A very dilute solution of the iodate, while cold, was carefully treated 

 with sulphurous acid. When an amount sufficient to remove the 

 brown color due to free iodine had been added, the solution was warmed 

 until the odor of sulphur dioxide could not be detected. The iodine 

 was then determined as silver iodide. (See table 89.)
