Identities of the components in a mixture may be determined by a technique called spiking. Suppose you had run a gas chromatogram on your product and had then deliberately added a drop of a known sample of 3-methylcyclohexene to a drop of your product. What would you expect the new chromatogram to show you?
The melting point (mp) range of reference compound A is 320-340°C. The mp range of a 1:1 mixture of a sample of A with a sample of unknown compound B is found to be 140-300°C. Do the samples consist of identical compounds? A)Yes, because the mp of the mixture is lower than the mp of pure A. B) Not enough information is given to answer the question C) Yes, because they melt over a broad range. D) No, because the mp of the mixture is lower than the melting point of pure A.
3. Correlate the structures of the standard food dyes to their relative position in the paper chromatogram.

4. When performing a melting point onsolid compound using a melting point apparatus, two melting point determinations were made, One sample, which was 1 mm in height in the capillary, possessed a melting point of 133.0-133.5°C. The other sample was 10 mm in height. What would you expect the approximate melting point to be for this sample, assuming identical heating rates of 1°/min? (Hint: heat is applied from the bottom of the sample) (Give an actual numerical approximation!)(Hint: at what temperature would 1g of ice start melting at? At what temperature would 10g of ice start melting at?)
How else can chromatography be used? None of these answers are correct. To wash (or remove) unwanted solvents from a mixture. To identify or exclude components in a mixture. To generate IUPAC names for hydrocarbons.
ef Correlate the structures of the standard food dyes to their relative position in the paper chromatogram. Refer to the structures shown below. H3C. *Na O O HO.

How did you arrive at this conclusion? Differentiate normal phase chromatography from reverse phase chromatography. From which of the two governs the experiment you did in thin layer chromatography of plant pigments? How do you say so?
3. What is particulate gravimetry? When do we use this technique? 4. What are the conditions for a successful gravimetric analysis. 5. Define nucleation. What conditions are important for this stage.
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.
