Hint: When glucose is treated with dilute NaOH, it converts the aldehyde group of glucose into the ketone group, so a ketose sugar forms. When the ketose sugar is treated with NaOH an epimer of glucose forms or again glucose can also form. All the reactions are reversible.

What does NaOH react with?

Sodium hydroxide reacts with strong acids (hydrochloric, sulfuric or nitric), water, and moisture to rapidly release heat. Sodium hydroxide reacts with metals (aluminum, lead, tin or zinc) to form flammable and explosive hydrogen gas.

What molecules react with NaOH?

NaOH reacts with acid to produce a water and an ionic compound. For example, when sodium hydroxide reacts with hydrochloric acid (HCl), the hydroxide ion from NaOH reacts with the hydrogen ion in HCl to form water (H2O). In a similar way, sulphuric acid (H2SO4) is neutralised by sodium hydroxide.

What does sucrose react with?

Chemical Properties of Sucrose Sucrose can undergo a combustion reaction to yield carbon dioxide and water. When reacted with chloric acid, this compound yields hydrochloric acid, carbon dioxide, and water.

Is sucrose a white sugar?

Sucrose is crystallised white sugar produced by the sugar cane plant and can be found in households and foods worldwide. Sucrose is a disaccharide made up of 50% glucose and 50% fructose and is broken down rapidly into its constituent parts. Due to its glucose content, sucrose has a GI value of 65.

What does not react with sodium hydroxide?

Phenol is an acid but does not react with sodium bicarbonate solution.

Is sucrose soluble in ethyl alcohol?

4.5 Solubility Sucrose octaacetate is readily soluble in organic solvents like acetonitrile, benzene, pyridine, and methanol. It has a solubility of about 12% (v/v) in 95% ethanol at room temperature [6].

Does NaOH react with OH?

No. Alcohols are very weak acids and do not react with NaOH.

What can you not mix with sodium hydroxide?

Incompatible Materials: Highly reactive. Reacts violently with: many chemicals, including, water, organic acids (e.g. acetic acid), inorganic acids (e.g. hydrofluoric acid), oxidizing agents (e.g. peroxides), metals (e.g. aluminum).

Does sucrose have carbonyl group?

All monosaccharides have free ketone or aldehyde group. this means that they are all reducing sugars. Maltose and sucrose are disaccharides, which means that they are made up of two monosaccharides.

Article first time published on

What is sucrose chemistry?

Sucrose is a disaccharide, or two-part molecule, formed by linking the monosaccharide sugars glucose and fructose. Honey–mostly a mixture of sucrose, glucose, and fructose–is formed when honeybees digest plant nectars using enzymes called invertases to break apart the sucrose molecules.

Does sucrose react with acids?

With concentrated sulfuric acid, granulated table sugar (sucrose) performs a degradation reaction which changes its form to a black solid-liquid mixture.

Is sodium acetate NaOH reactive?

Explanation: Acetic acid, CH3COOH , will react with sodium hydroxide, NaOH , to produce sodium acetate, CH3COONa , and water.

What is true with respect to sodium hydroxide?

Physical properties. Pure sodium hydroxide is a colorless crystalline solid that melts at 318 °C (604 °F) without decomposition, and with a boiling point of 1,388 °C (2,530 °F). It is highly soluble in water, with a lower solubility in polar solvents such as ethanol and methanol.

What's the difference between sodium hydroxide and calcium hydroxide?

The NaOH solutions exhibited higher capability to remove lignin than the Ca(OH)2 solutions. NaOH can be dissolved completely in the water and 70% glycerol, while Ca(OH)2 can be hardly dissolved in the water and form turbid liquid in 70% glycerol.

Is sucrose a disaccharide?

disaccharide, also called double sugar, any substance that is composed of two molecules of simple sugars (monosaccharides) linked to each other. … The three major disaccharides are sucrose, lactose, and maltose.

Is sucrose polar or nonpolar?

Like water, the sucrose molecule has bonds between the oxygen and hydrogen atoms. And like water, the area near the oxygen is slightly negative and the area near the hydrogen is slightly positive. This gives sucrose many areas of positive and negative charge and makes sucrose a polar molecule.

Is sucrose ionic or covalent?

Usually there is unequal electron sharing and covalent bonded molecules show some polarity. Many organic molecules have polar interactions, which are characteristically weak. Hence, sucrose has strong covalent bonds holding a given sucrose molecule together but weak polar bonds between adjacent molecules.

Is sucrose soluble in petroleum ether?

3. Table sugar, sucrose, is soluble in water, but is insoluble in petroleum ether (an organic solvent similar to gasoline).

Why is sucrose insoluble in ethanol?

Sugar dissolves well in water because water is very polar and interacts with the polar areas of sucrose. Sugar does not dissolve very well in alcohol because alcohol has a large part that is pretty non-polar.

Why is sucrose insoluble in dichloromethane?

no (Although dichloromethane and sucrose are both polar molecules, dichloromethane is not an organic solvent (sucrose is an organic compound). Additionally, sucrose has hydrogen bonding which is much more polar than the dipole-dipole interactions of dichloromethane. Thus, sucrose does not dissolve in dichloromethane.)

Which of the following oxide does not react with NaOH?

CaO being basic oxide will not react with base, NaOH.

Which of the following oxide is not accepted to react with sodium hydroxide?

Explanation: CaO being a basic oxide does not react with NaOH, however SiO2 (acidic oxide), BeO (amphoteric oxide) and Br2O3 (acidic oxide) react with NaOH.

Which of the following oxide will react with NaOH?

Cl2O7.

What chemicals Cannot be mixed?

• Bleach and Ammonia = Toxic Chloramine Vapor. Bleach and ammonia are two common household cleaners that should never be mixed. …
• Bleach and rubbing alcohol = Toxic chloroform. …
• Bleach and vinegar = Toxic Chlorine Gas. …
• Vinegar and Peroxide = Paracetic Acid. …
• Peroxide and Henna Hair Dye = Hair Nightmare.

What pH is NaOH?

BaseNormalitypHSodium hydroxide (caustic soda)N14.0Sodium hydroxide0.1 N13.0Sodium hydroxide0.01 N12.0Sodium metasilicate0.1 N12.6

Does NaOH react with air?

NaOH (sodium hydroxide), when exposed to the air, will react with the carbon dioxide in air, to form sodium carbonate (see equation). This means that sodium hydroxide as a solid or in solution will loose its strength with time and degree of exposure and solutions of NaOH will need to be standardised.

How does ethanol react with sodium hydroxide?

When ethanol (C2H5OH) is added to aqueous sodium hydroxide (NaOH), no reaction occurs. This is because aqueous sodium hydroxide contains sodium ions (Na+) and hydroxide ions (OH−). … The reaction of ethanol with sodium metal is an acid-base reaction.

Does NaOH react with phenol?

Phenol reacts with sodium hydroxide solution to give a colourless solution containing sodium phenoxide. In this reaction, the hydrogen ion has been removed by the strongly basic hydroxide ion in the sodium hydroxide solution.

Does benzoic acid react with NaOH?

Due to its acidic nature, benzoic acid can undergo a reaction with NaOH as follows, resulting in the carboxylate salt sodium benzoate.

Why does sucrose not react with Fehling solution?

Benedict and Fehling’s reagent are two solutions used to determine the reducing capability of a sugar. … The reason why sucrose is a non-reducing sugar is that it has no free aldehydes or keto group. Additionally its anomeric carbon is not free and can’t easily open up its structure to react with other molecules.
