Do you predict that maltose will reduce cupric ion in Fehling

Expert Solution

In chemistry, the Benedict's reaction identifies reducing sugars (those with their free anomeric C-OH), such as glucose or maltose. In alkaline solutions, can reduce Cu2 + which is blue to Cu +, which precipitates from the alkaline solution as Cu2O red-orange.

Benedict's reagent comprises: Cupric sulfate, Sodium Citrate, Anhydrous Sodium Carbonate. (NaOH is used in addition to alkalize the medium)

The basis of this reaction is that in an alkaline medium, the cupric ion (awarded by the cupric sulfate) can be reduced by the effect of sugar aldehyde group (CHO) to form Cu+. This new ion is observed as a brick-red colour precipitate corresponding to cuprous oxide (Cu2O).

The alkaline medium facilitates a linear form, since the sugar ring forms a solution. Once the sugar is linear, the aldehyde group can react with the cupric ion in solution.

In short, there is talk of reducing sugars when they have their free anomeric OH C, and these are what give positive proof of Benedict.

Indicators Starch and maltose when dissolved in water are colorless. To determine if starch or maltose are present chemical indicators must be used for the researcher to qualitatively visualize the presence of starch and maltose. The indicators used in this experiment are listed below. IKI (potassium iodide) starch test is an indicator of starch. In a positive IKI test a blue-black color change occurs, even if the blue-black color disappears after the addition of IKI. A negative result is recorded...

Should the Bohr model predict the correct emission lines for the He+ ion ? Why or why not?

Should the Bohr model predict the correct emission lines for the He+ ion ? Why or why not? Use the Bohr model to predict some of the visible emission lines of the He+ ion. Hints: see your text for the correct equation concerning the energies of the Bohr model orbits which includes the nuclear charge Z. Then calculate the wavelengths in nm corresponding to the transitions n=4→3, and n=6→4. Can either of these be observed in your He emission spectrum?
