1.	Chloroform is kept with a little ethyl alcohol in a dark coloured bottle. Why?
Answer» Solution :(i) Chloroform 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. (II) With the use of 1% ethanol we can stabilise chloroform, because ethanol can convert the poisonous `COCl_2`gas into non poisonous diethyl CARBONATE. `COCl_2 + 2C_2 H_5OH to CO(OC_2H_5)_2 + 2HCl`
