CARBONIC ACID. 295 Chloro-carbonic acid or phosgene gas {CO, CI) isformed, under the influence of light, from equal volumesof chlorine and carbonic oxide. It is an acid body of apungent odor, and is decomposed by water. It is re-garded as carbonic acid, in which one atom of oxygenis replaced by one of chlorine. LECTURE LV.
