Q. Nesslers reagent is

$KH g I_{4}$

$K_{2} H g I_{4} + N H_{4} O H$

$K_{2} H g I_{4} + K O H$

$KH g I_{4} + N H_{4} O H$

Nesslers reagent $= K_{2} H g I_{4} + K O H$ $2 K_{2} H g I_{4} + N H_{4} Cl + 4 K O H \to$ $iodide of Milion s base (brown ppt .) N H_{2} H g O H g I + 7 K I + K Cl + 3 H_{2} O$ Note Nesslers reagent is used tor detection of ammonia. It gives brown ppt. with ammonium salt.
