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.
Does sucrose react with NaOH?
The sucrose in the molasses is hydrolyzed to glucose and fructose by invertase
What does NaOH not react with?
Boron
does not react with aqueous NaOH, However, it forms borates when fused with alkalies.
What does sucrose react with?
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. Upon hydrolysis, the glycosidic bond linking the two carbohydrates in a C

molecule is broken, yielding glucose and fructose.
What happens when NaCl reacts with NaOH?
Explanation: Usually what happens in a reaction with two compounds is
double replacement (the partner switch)
, where the anions and cations switch. common table salt is NaCl. So if NaCl and NaOH go through double replacement, the end result will be the same because they both have Na as a cation.
How does Caramelisation happen?
Caramelization is a slow cooking process that occurs
when sugar is cooked over low heat, causing a change in both appearance and flavor
. Through a process called pyrolysis, during caramelization, the sugar in a food oxidizes, taking on a brown color and a rich, slightly sweet and nutty flavor.
Is NaOH a weak base?
Sodium hydroxide (NaOH) is strong base because it fully dissociates in water to produce hydroxide ions. … While weak bases produce fewer hydroxide ions, making the solution
less basic
.
Does mg react with NaOH?
Under normal conditions,
magnesium metal does not react with an aqueous solution of sodium hydroxide
.
Why the formula of sodium hydroxide is NaOH?
Sodium Hydroxide belongs to the category of inorganic compounds and is usually found in the form of a white solid at room temperature. This chemical compound consists of
sodium Na
+
cations and hydroxide OH
−
anions
. Sodium Hydroxide chemical formula is written as NaOH. … Sodium Hydroxide is one of the simplest hydroxides.
Does NaOH react with oxygen?
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.
What happens when NaOH reacts with water?
When sodium hydroxide (NaOH) dissolves in water,
it separates into positively – charged sodium ions (cations) and negatively – charged hydroxide ions (anions)
. These ions move around in the water, free and independent of each other, though cations tend to be surrounded more closely by anions and vice versa.
Is Salt caustic?
Salt is essential for life in general, and saltiness is one of the basic human tastes. … Its major industrial products are
caustic soda
and chlorine; salt is used in many industrial processes including the manufacture of polyvinyl chloride, plastics, paper pulp and many other products.
Why is sucrose bad for you?
When sucrose is digested it breaks down into fructose and glucose, which then go their own separate ways in your body. This process raises your blood sugar, and
too much can rupture blood vessels
and cause mouth problems such as cavities and gum disease.
What is the source of sucrose?
Sucrose is a naturally occurring sugar found in various amounts in
plants like fruits, vegetables and nuts
. Sucrose is also produced commercially from sugar cane and sugar beets.
What happens when you add HCl to sucrose?
Reaction 2: Sucrose is protonated by HCl then
undergoes a hydrolysis reaction to yield glucose and fructose as the final products
. Reaction 1: Sucrose is broken down by invertase into glucose and fructose via a hydrolysis reaction. … The sugar is the reducing agent and DNS is the oxidizing agent.
