Lactic acid is an important pharmaceutical product that is manufactured by fermentation of glucose. To separate the lactic acid from the biomass, filtration followed by centrifugation is employed. A mix containing 23% by mass lactic acid enters the filtration unit at the rate of 6,456 kg/hour. After filtration, the sludge of lactic acid/biomass contains 12 % by mass lactic acid and the filtrate itself contains 100% lactic acid by mass. The sludge then goes to the centrifuge where the solids generated contain 8% lactic acid by mass and the liquid portion stream has 100% lactic acid by mass. Calculate mass flow rate in kg/hour of the stream leaving the filtration unit containing pure lactic acid. [report number with one decimal e.g. 100.4]

Hydrogen peroxide solutions can easily be decomposed by dust, trace amounts of metals or light. It istherefore necessary to periodically determine the purity of the peroxide solutions.This can be done via a redox titration as follows: The density of a particular surgical grade hydrogen peroxide solution is 1.11g.cm-3. Exactly 10 mL of this solution was pipetted and quantitatively transferred, along with a sufficientamount of a dilute sulphuric acid solution, into a 250.00 mL volumetric flask and made up to the mark. A 25.00 mL portion of this diluted solution is pipetted into a conical flask, and titrated with a0.372 M KMnO4 solution. The endpoint of the titration is determined when the colourless solution in the conical flask turns apersistent bright pink due to the presence of excess permanganate ions. The average titration value is 26.20 mL of the KMnO4 solution 1.Determine the percentage of the hydrogen peroxide in the solution sample.2.

A 25mL volumetric pipet is used to deliver a sample of the stock solution marked “0.6000M X2SO4” into a 100mL volumetric flask. Distilled water is added to the flask until it is about 3/4thfull, the solution is mixed well, then more water is added to fill it up to the calibration mark, then it is mixed again. Calculate the concentration of X+ion in the dilute solution made above.

Meztiza, a beer cocktail, is prepared by mixing rum, beer, and cola. Compute the finalconcentration(%w/v) of ethanol in meztiza if 100.0 mL of beer was first mixed with 5.0 mL rum andbefore finally diluting it with cola to produce 200.0 mL of the beer cocktail. ( a beer contains about 4.50% (v/v) of ethanolfermented by yeast from sugars while rum contains about 40.0% (v/v) ethanol. Meanwhile, arubbing alcohol is also an alcohol solution which contains 70.0 %(v/v) isopropyl alcohol fermentedby a bacterium instead of a yeast)
