Question

distinguish between hcl and so2​

Answer 1

Answer:

Look up in the NIST Chemical WebBook the vapor pressures of both gases as a function of temperature. Along a wide rage (200-250K) of temperature, the vapor pressure of gaseous SO2 remains considerably smaller than that of gaseous HCl. Therefore, both compounds may be separated by trap-to-trap distillation from a gaseous mixture of both components.
