It is part of the experiment to determine the sugar present... it does not react with non reducing sugar.

Why the Benedict's solution turn brick red colour when testing glucose content in urine?
Copper (I) oxide: Cu2O
How do you differentiate between reducing and non reducing sugar?
Add benedicts solution to the sample you are testing, heat gently for 5 minutes, and if reducing sugars are present, the solution turns red (if concentration of reducing sugars is high) and if its not as high it could turn green-yellow-brown ish the closer to red, the higher the concentration of reducing sugars. it will stay blue if none are present
What is albustix is used for?
Clinistix is a commercially available product for testing for of glucose in urine. It turns purple if glucose is present. Albustix is a commercially available product for testing for the presence protein in urine.
What is the pH of gold testing solution?
nitric asid
What tests require plasma for testing?
Diabetes is the test that requires plasma for testing. Plasma is a glucose test used to test blood sugar levels for diabetes diagnosis.
What chemical is used to test for sugars?
Depends on the Sugar: Reducing sugars a normally monosaccharides but there are some disaccharides too like maltose. If its a reducing sugar then you would add Benedicts Reagent (alkaline copper(II) sulphate). You then heat it. if a reducing sugar is present then a precipitate is formed that will be red/orange. A Non-reducing sugar like Sucrose can be tested by first adding benedicts and heating. if no change is present you then add hydrochloric acid to hydrolyse the glycosidic bond. you then add a hydrogen carbonate solution to neutralise the acid. Then repeating the Benedicts and Heating process.
How does sodium chloride react with Benedicts?
The Benedict reagent is not for sodium chloride testing.

Copper (I) oxide: Cu2O
Why is hydrochloric acid used when testing for non-reducing sugars?
to hydrolise sucrose solution into a monosaccharide ( glucose and fructose )
What chemical would you use to test food for glucose?
A fairly simple test is using clinistix- these are used for diabetes testing and available in any chemists, just dip them into any solution thought to contain glucose and they will turn from pink to purple (there are other colours available though)
Diabetes Testing?
Diabetes testing is important for effectively managing the disease. Diabetics should perform their own testing daily with a glucose meter. A1C testing is ordered several times a year by doctors to check overall glucose levels.
What are the differences between different types of diabetes testing equipment?
Home blood glucose test measures the amount of a type of glucose in the body. It involves using testing strips, where you place a drop of blood to determine glucose levels.
I have been testing my glucose twice a week. My meter read 127 this morning. I want to know what my glucose level should be. I am 81.?

The Chemistry Of Glucose Testing Strips?
Glucose testing strips have given diabetics the ability to test glucose levels in the blood from any location with very little effort. The disposable strips are read by a special device that can use one of two different methods to determine the glucose levels of the blood. A glucose testing strip is just one of the items that must be used with a glucose testing meter. The other item is a disposable needle known as a lancet that actually draws the drop of blood for the testing strip from the finger or arm. A glucose testing strip is covered in a number of chemicals and enzymes. The exact combination can vary depending on the meter or the proprietary formula of the manufacturer. The strips most commonly contain either glucose oxidase or glucose dehydrogenase. These enzymes will interact with the glucose in the blood on the testing strip along with other chemicals mixed with the enzymes. One possible result of the combination is a colored stain on the test strip. The other possibility is that the glucose and the chemicals will be converted into a conductive material called ferricyanide. Glucose testing strips that rely on changing colors are fed into a glucose meter. This meter uses a light and a sensor to measure the reflectivity of the stain on the end of the strip. The exact color of the chemical reaction can then be judged electronically and the blood glucose level can be determined. Glucose testing strips that create ferricyanide are fed into a glucose meter that sends an electrical current through the end of the strip. A higher level of glucose in the blood means that the strip will be more conductive and will allow more electricity to pass through. The measurement of the current determines the glucose level that is displayed. The accuracy and convenience of glucose testing strips has slowly increased over the years. The amount of blood that is required to cause a reaction on each strip has also been reduced dramatically. Hospitals even use a version of testing strips that allow many patients to be tested in sequence. The results from the device are wireless transmitted to hospital computers.
What is Clinistix and Albustix and why it is used for?
Clinistix is a commercially available product for testing for of glucose in urine. It turns purple if glucose is present. Albustix is a commercially available product for testing for the presence protein in urine.
