The reason as to why the samples can often be separated into their components by chromatography is to be stated. Concept introduction: Chromatography is the technique used to identify the components of a mixture. The separation of mixture is based upon the polarity of the components present in the mixture. The division of the distance covered by the component of a compound to the distance covered by solvent in the chromatography technique is known as the R f value. The full form of R f value is retention value.

Question

5. A solution of sucrose is fermented in a vessel until the evolution of CO2 ceases. Then, the product solution is analyzed and found to contain, 45% ethanol; 5% acetic acid; and 15% glycerin by weight. If the original charge is 500 kg, evaluate; e. The ratio of sucrose to water in the original charge (wt/wt). f. Moles of CO2 evolved. g. Maximum possible amount of ethanol that could be formed. h. Conversion efficiency. i. Per cent excess of excess reactant. Reactions: Inversion reaction: C12H22O11 + H2O →2C6H12O6 Fermentation reaction: C6H12O6 →→2C2H5OH + 2CO2 Formation of acetic acid and glycerin: C6H12O6 + C2H5OH + H₂O→ CH3COOH + 2C3H8O3
