The same amount of bromide was added to each specimen(Roughan, J.A., Roughan, P.A. and Wilkins, J.P.G., 1983, Analyst, 108: 742).Tomato: 777 790 759 790 770 758 764 ug/gCucumber: 782 773 778 765 789 797 782 ug/g(a) Test whether the recoveries from the two vegetables have variances which differ significantly.(b) Test whether the mean recovery rates differ significantly.
In a chromatographic separation of two components A and B. Component A has a higher Rf value than component B. This implies that: A. Component B has a higher affinity than A for the mobile phaseB. component B elutes first in the columnC. A has a higher affinity than B for the mobile phaseD. Component A has a higher affinity than B for the stationary phase.
Why is the spectrophotometer set at 100% T using the FeCl3 solution rather than distilled water? O The iron chloride solution is used as the blank bećause aspirin is not soluble in distilled water. The iron chloride solution is used as the blank because distilled water will interfere with the absorbance readings. The iron chloride solution is used as the blank because that is the solvent which is present for all solutions. The iron chloride solution is used as the blank because distilled water has no color.
1. From spinach, the chromatographic analysis will yield two major substances: (a) B-carotene (C40H56), which will separate from the spinach mixture to form a yellow band, and (b) chlorophyll A (CSSH72MGN4OS), which will separate from the mixture to form a green band. i. Describe the characteristics and draw structures of these molecules. ii. From the spectrophotometric analysis, what wavelength (Amax) would you expect ß-carotene (C40H56) to absorb? What wavelength would chlorophyll A (CssH72MgN4O5) absorb?
