✦ Synopsis

AFANAS'ICV~ reported that chloramine-13 is a good suhstitutc for chloraminc-T in analytical chemistry. Chloraminc-B reacts with potassium iodide in the prcsencc of an acid: C,H,SO,N(Na)CI -+ z HI --= C,H,SO,NH, -j-NaCl + 1 1.

In acid medium potassium iodiclc reacts with potassium iodatc, potassium metapcriodotc, potassium bromate, potassium dichromntc, hydrogen perosidc, chloraminc-'1 and potassium pcrmangnnatc according to the following equations : KIO, -I-5 ICI + 3 H&J, ICIO, + KRrO, i Tcr _t 4 I-I,SO, -i-0 TCI + 3 I-f,%>, K,Cr,O, $ G ICI + 7 I-i,SO, I-1,0, -+-z I<1 +
