C_{6} H_{5} N H_{2} + N a N O_{3} + H C I \to C_{6} H_{5} N C I + H_{2} O + N a O C I

H g_{2} I_{3} + 2 N H_{3} = N H_{2} [H g_{2} I_{2}] + N H_{4} I

C_{6} H_{5} N H_{2} + N a N O_{2} + H C I \to C_{6} H_{5} N C I + H_{2} O + N a C I

2 H g (N O_{2})_{2} = 2 H g + 4 N O + 2 O_{2}

2 K H g I_{2} = 2 K I + 2 H g I
