Why a small amount of ethyl alcohol is usually added to chloroform bottlkes ?

Text Solution

Verified by Experts

Chloroform oxidised to phosgene in the presence of air or light. Ethyl alcohol changes phosgene to harmless ethyl carbonate. So, alcohol decreases the oxidation of chloroform to phosgene.
` 2C_2 H_5 OH +CoCl_2 to (C_2 H_5 )_2 CO_3 +2HCl `
Hence, ethyl alcohol is added to chloroform bottles.
