Does amylase change color when reacting to Benedict's reagent?
Amylase does not change color when reacting with Benedict's reagent. Benedict's reagent is mainly used to test for reducing sugars like glucose, which would turn from blue to brick-red when reacting with the reagent. Amylase is an enzyme that breaks down starch into smaller sugars, but it does not directly react with Benedict's reagent to produce a color change.
What sugar might be present in a sweet tasting food that tests negative with the Benedicts reagent?
Sucrose. Sucrose is a disaccharide therefore does not have free electrons in the sugar to react with the Benedict reagent. Glucose has free electrons therefore shows positive with the Benedict reagent.
What are the components of Benedict's reagent?
Benedict's reagent contains copper sulfate, sodium citrate, and sodium carbonate. These components are used to test for the presence of reducing sugars, producing a color change from blue to green, yellow, orange, or red depending on the amount of reducing sugar present.
What color does acetone with Benedict's reagent have?
Acetone itself does not react with Benedict's reagent, which is primarily used to detect reducing sugars. Therefore, when acetone is mixed with Benedict's reagent, there would be no significant color change, and the solution would likely remain blue. The blue color indicates the absence of reducing sugars, as acetone does not possess the necessary functional groups to produce a positive result with this reagent.
Why Na2Co3 is added with CuSo3 at preparing benedict's reagent?
just for FUN!
What color is Benedict's reagent originally?
Benedict's reagent is originally blue in color.

Amylase is an enzyme that breaks down starch into smaller sugars, but it does not directly react with Benedict's reagent to produce a color change.
Which sugar gives a negative reaction to Benedict reagent?
Sucrose gives a negative reaction to the Benedict's reagent test because it is a non-reducing sugar. Benedict's reagent is used to test for the presence of reducing sugars, which have the ability to reduce the copper ions in the reagent. Since sucrose does not have this ability, it does not give a positive reaction.
Will whole milk react with benedict's reagent?
No, whole milk will not react with Benedict's reagent because milk does not contain reducing sugars like glucose or fructose, which are necessary for the reaction with Benedict's reagent to occur. Benedict's reagent is used to test for the presence of reducing sugars in a solution.
What is the chemical formula for quantitative Benedict's reagent?
Benedict's reagent is an aqueous solution of copper (II) sulfate, sodium carbonate, sodium citrate dihydrate and 2,5-difluorotoluene.
What sugar might be present in a sweet tasting food that tests negative with the Benedicts reagent?
Sucrose. Sucrose is a disaccharide therefore does not have free electrons in the sugar to react with the Benedict reagent. Glucose has free electrons therefore shows positive with the Benedict reagent.

List two advantages in using the clinitest reagent in preference to Benedict's reagent?
The Clinitest reagent is a self test so it does not need to be performed in a hospital setting or by a nurse or doctor. The Clinitest reagent has proven to be more accurate than the Benedict's reagent.
What substance is present when Benedict reagent turns red?
glucose
Why Na2Co3 is added with CuSo3 at preparing benedict's reagent?
just for FUN!
What causes Benedict's reagent to turn red?
This is due to the reduction of the cupric (Cu2+) ions in Benedict's reagent to cuprous form (Cu1+) by reducing sugars, forming cuprous oxide (Cu2O), which is a brick red precipitate. This is why Benedict's test is a good way to detect reducing sugars.
