What does the HCl acid do in the Benedict's Test for non-reducing sugars?
Wiki User
∙ 11y ago
Dilute HCL solution hydrolyses non-reducing sugar (sucrose) into its components; monosaccharides; glucose and fructose, and then solution must get neutralised by a base since benedict's solution won't work in acidic environments. After this Cu II ions in benedict's solution could get reduced to Cu I by glucose. Brick red colour is observed when Cu I Oxide (precipitate) forms.

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 can you test gold to see if its real?

Does obsidian bubble when doing a acid test?
it does
What do geologists use the acid test for?
Because its cool

What is mucic acid test?
A music acid is an aldaric acid obtained by nitric acid oxidation of galactose. A music acid test helps distinguish galactose and lactose from other reducing sugars.
How is Benedicts test used to determine the glucose content of a sample of urine in blood?
Aqueous is mixed with Benedict's reagent, a solution of copper sulfate, sodium hydroxide, and tartaric acid. The mixture is heated. Carbohydrates which react with Benedict's reagent to reduce the blue copper (II) ion to form a brick red precipitate of copper (I) oxide are classified as reducing sugars.
What is a saccharinic acid?
A saaccharinic acid is an acid derived from various sugars.
Are amino sugars part of amino acids?
no amino sugars are not part of amino acid
In idioms What does acid test mean?
Acid test or litmus test means to try it an see. The acid test of a cake is eating it. The acid test of a new idea is seeing if it works.
What acid do you use for the acid test?
what acid do you use to test gold
What is the anaerobic breakdown of sugars into alcohol?
Fermentation is the anaerobic breakdown of sugars into alcohol, carbon-dioxide, and lactic acid.
What is an acid test?
An acid test is a rigorous test of the quality or value of something.
How do Ph indicators test for sugar fermentation?
When organisms ferment sugars they usually produce lactic acid as a byproduct. This lactic acid production lowers the pH of the media the bacteria is grown in. The pH indicator changes the media color in response to the decreasing pH from the lactic acid production.
What test is useful in diagnosis of gout?
It is a test for uric acid. High Uric acid in he blood can lead to the formation of uric acid crystals which are responsible for the pain.
