# Of carbon disulfide, rubber latex, and petroleum spirit, which are pure substances, and which are mixtures?

All except carbon disulfide, $C {S}_{2}$, are mixtures......
Petroleum is a mixture of isomers; even the petroleum spirit supplied in the lab is a mixture of ${C}_{4} - {C}_{6}$ hydrocarbons. Rubber latex is a polymer, and vulcanizing solution is a proprietary mixture of sulfur and other materials......
On other hand, $C {S}_{2}$ is a volatile solvent with a particularly foul odour, and is particularly flammable.
