A mixture of two high-boiling organic acids is to be separated from nonvolatile impurities by steam distillation at 373 K under a total pressure of 20 kPa. The organic acid mixture contains
30 mol% low boiling acid and 70 mol% high boiling acid and at 373 K the vapour pressures of
the two acids are 2.7 kPa and 1.1 kPa, respectively. The acid mixture obeys Raoult's law and
are immiscible with water. Determine the kilograms of steam required per kmol of acid
recovered

Answer asap need it by wednesday morning carry out the following calculations on ph and ka of from data. i. calculate the ph of 0.02m hcl ii. calculate the ph of 0.036m naoh iii. calculate the ph of 0.36m ca(oh)2 iv. calculate the ph of 0.16m ch3cooh which has ka = 1.74 x 10-5 mol dm-3 v. calculate ka for weak acid ha which has a ph of 3.65 at 0.30m concentration vi. calculate the ka of a solution made by mixing 15.0 cm3 0.2m ha and 60.0 cm3 0.31m a-. [ph= 3.80] vii. calculate the ph of a solution made by mixing 15.0 cm3 0.1m naoh and 35.0 cm3 0.2m hcooh. [ka = 1.82 x 10-4 m]
