Why does non reducing sugar change colour when you add hydrochloric acid and hydrogen carbonate crystals?

The non-reducing sugar changes color when hydrochloric acid and hydrogen carbonate crystals because the non-reducing sugar gets oxidized as it gives an electron to the reducing agent.

What is difference between Benedict's Solution and Hydrochloric Acid?
Hydrochloric acid is HCl. Benedict's solution is a solution of sodium citrate, sodium carbonate, and copper sulfate that changes from blue to yellow or red in the presence of reducing sugars, such as glucose. Also called Benedict's reagent.
How hydrochloric acid affect non-reducing sugar?
A non-reducing sugar can be hydrolyzed using dilute hydrochloric acid. After hydrolysis and neutralization of the acid, the product is a reducing sugar. So acidic hydrolysis can convert the non-reducing sugars (disaccharides and polysaccharides) into reducing simple sugars.
What does hydrchloric acid do?
Hydrochloric acid can act as a Bronsted acid, an oxidizing agent and as a reducing agent.
How are hydrochloric acid and sulfuric acid similar?
Obviously both of them are acids. Both of these compounds can donate protons to other compounds. Both of these compounds can undergo red-ox reactions and participate in them either as oxidizing or reducing agents. Both of these compounds evolve gaseous hydrogen from the reaction with metals, such as magnesium and zinc.
What will happen if hydrochloric acid is used instead of sulfuric acid in permanganometric titrations?
Hydrochloric acid being a very good reducing agent, will interfere with the titrations and be oxidised to chlorine by potassium permanganate. Hence sulfuric acid is used, and not HCl.
What is the purpose of sodium hydrogen carbonate solution in the non-reducing sugar reaction?
fire extingusher

Why is hydrogen used in metallurgy?
As hydrogen is a reducing agent it is used in metallurgy
What does the presence of calcium carbonate indicate?
For example degradation of a pipe by reducing the diameter.
Which ELEMENT is a reducing agent?
Hydrogen is a reducing element, or reducing agent. More specifically, atomic Hydrogen, ie; singular Hydrogen atom, because it does not have a pair of electrons, only one, and therefor will accept or gain an electron to fill its valency of 2 electrons, a covalent bond. This type of Hydrogen is sometimes refered to as nascent Hydrogen-or newly formed Hydrogen from a chemical reaction to produce this atomic Hydrogen. Hope this helps.

What reacts with metals to produce hydrogen gas?
Metals often form hydrides and are found widely in chemistry. notable examples are LiAlH4 potent reducing agent in organic chemistry and NaH powerful base ~50 PKa. in addition hydrogen can adsorb onto metal surfaces. this is important in the catalysis of hydrogenation reactions where Hydrogen gas is reacted with unsaturated compounds by using a platnium surface(many other conditions/metal catalysts are also used)
Is it possible to use hydrogen as a reducing agent for ion oxide to get the metal iron?
No. On the contrary - iron will reduce hydrogen oxide to hydrogen
Whats hydrogen used for?
Its used for processing foods. Hydrogen is used in massive quantities in the petroleum and chemical industries. In a petrochemical plant, hydrogen is used for hydrodealkylation, hydrodesulfurization, and hydrocracking, all methods of refining crude oil for wider use. In the food industry, hydrogen is used to hydrogenate oils or fats, which permits the production of margarine from liquid vegetable oil. Hydrogen is used to produce Methanol and hydrochloric acid, as well as being used as a reducing agent for metal ores.
