Knowing that the extraction efficiency of an organic solvent over an aqueous solution can be measured by the following relationship: [A]i (Vaq / Vorg K+ Vaq)' · [A]o a. Compare the fraction of propanoic acid (C3H6O2) that can will remain in the aqueous solution after one extraction if 50.00 mL of the aqueous solution is extracted by 100.00 mL of heptane for which the KD value over water is 5.5. b. What will be this fraction of propanoic acid if the 100 mL are replaced by 4 volumes of 25.00 mL of heptane in four consecutive extractions? c. Is it more effective to adjust the aqueous solution to pH 3.0 or pH 8.0? Why?
Carbohydrates
Carbohydrates are the organic compounds that are obtained in foods and living matters in the shape of sugars, cellulose, and starch. The general formula of carbohydrates is Cn(H2O)2. The ratio of H and O present in carbohydrates is identical to water.
Starch
Starch is a polysaccharide carbohydrate that belongs to the category of polysaccharide carbohydrates.
Mutarotation
The rotation of a particular structure of the chiral compound because of the epimerization is called mutarotation. It is the repercussion of the ring chain tautomerism. In terms of glucose, this can be defined as the modification in the equilibrium of the α- and β- glucose anomers upon its dissolution in the solvent water. This process is usually seen in the chemistry of carbohydrates.
L Sugar
A chemical compound that is represented with a molecular formula C6H12O6 is called L-(-) sugar. At the carbon’s 5th position, the hydroxyl group is placed to the compound’s left and therefore the sugar is represented as L(-)-sugar. It is capable of rotating the polarized light’s plane in the direction anticlockwise. L isomers are one of the 2 isomers formed by the configurational stereochemistry of the carbohydrates.
