Is Cellulose ketohexose or aldohexose? How does Cellulose give result in Seliwanoff’s test (any color change)?

Chemistry

Mamont248 [21]3 years ago
4 0

Answer:

Cellulose is an aldohexose

Explanation:

Cellulose is an aldohexose  , because , it has an aldehyde group present at one of the end .

Seliwanoff’s test

It is the test to differentiate between a ketose and an aldose .

The test is as follows -

If the sample is heated and it it readily gets dehydrated , then the sample is a ketose .

And , the reaction of   Seliwanoff’s reagent and  ketose , give a red color , which is the positive sign for the test .

But ,

the reaction of   Seliwanoff’s reagent and  aldoses , give a very light pink color .

How to find kc from % ionization
Lunna [17]
Well, percent ionization, simply allows you to find X which is the change in amount of substance into the final amount, it is dependent on the initial concentration of the substance present that is being dissociated.

For example, if the percent dissociation of CH3COOH is 1.5 % for an initial concentration of 0.15, then to solve for x, you would need to write percent as a decimal and solve.

% dissociation = X/Concentration of substance dissociated

0.015 = X/0.15

X = 0.0025.

Now since you know X, use the ice tables to solve for concentrations of species at equilibrium and plug in Kc expression.
