Meu professor passou um questionario sobre um experimento que fizemos, porem nao entendi uma pergunta, que é:

No item 9, por que se adiciona cloroformio ao final da reação? Por que aparece uma coloração violeta?

Experimento:
Colocar 2ml de solução de KI em um tubo de ensaio.
Adicionar 2ml de agua de cloro. Observar.
Adicione 2ml de CHCL3. Agitar. Observar a coloração.



E isso. Se alguem puder me ajudar. Obrigado
