Chloroform is stored in dark colured bottles. Explain in not more than two sentences.

Chloroform in the presence of ari and sunlight oxidises slowly to form a highly poisounous compound called phosgene or carbonyl chloride. `underset("Chloroform")(2HCl_(3)) + underset(Air)(O_(2)) overset(hv)(rarr) underset("Phosgene")(2COCl_(2)) + 2HCl` To avoid the oxidation or chlorofom it is kept in dark or yellow coloured bottles and filled up to the brim.

Chloroform is stored in dark coloured bottles. Explain in not more than two sentences.

In the presence of light, chloroform is oxidised to a highly poisonnous gas phosgene. `underset("Chloroform")(2CHCl_(3))+underset((Air))(O_(2))overset(light)tounderset("Phosgene")(2COCl_(2))+2HCl` In order to check this, chloroform must be kept in dark brown coloured bottles. Moreover, te bottles must be completely filled and well stoppered to check the entry of air.

Chloroform is kept with a little ethyl alcohol in a dark coloured bottle. Why?

1. Chlorofòrm is slowly oxidised by air in the presence of light to an extremely poisonous gas, carboxyl chloride (phosgene). it is therefore stored in closed dark coloured bottles completely filled so that air is kept out. 2. With the use of 1% ethanol we can stabilise chloroform, because ethanol can convert thepoisonous COCl 2 gas into non poisonous diethyl carbonate.
