BLUE BOTTLE EXPERIMENT

Question 1

• is a color-changing redox chemical reaction.
• An aqueous solution containing glucose, sodium hydroxide, methylene blue is prepared in a closed bottle containing some air.

Answer 1

Blue Bottle Experiment

Question 2

• It is made of 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms.
• can be called as aldohexose as well as dextrose.
• In the Blue Bottle Experiment alkaline solution of glucose acts as a reducing agent and reduces added methylene blue from a blue to a colourless form.

Answer 2

Glucose

C6H12O6

Question 3

Uses of Glucose

Answer 3

• Energy Source
• When consumed, it is broken down during cellular respiration to produce adenosine triphosphate (ATP).
• Blood Sugar Regulation
• Glucose plays a critical role in regulating blood sugar levels (blood glucose levels).
• Cellulose Synthesis in Plants
• is used to synthesize cellulose, a structural polysaccharide that forms the cell walls, providing rigidity and support to plant cells.
• Energy Drinks and Sports Nutrition
• contain large amounts of sugar ranging from 21 g to 34 g per oz.
• Examples: Gatorade, Red Bull, Monster Energy Drink

Question 4

• often known as Caustic Soda or lye
• common ingredient in cleaners and soaps.
• useful for its ability to alter fats, and it helps control pH, making it effective and practical for these applications.
• At room temperature, sodium hydroxide is a white, odorless solid

creates an alkali medium

Answer 4

Sodium Hydroxide

NaOH

Question 5

pH greater than 7

Answer 5

alkaline

Question 6

pH less than 7

Answer 6

acidic

Question 7

• As a medication, it is mainly used to treat methemoglobinemia
• Used to treat methemoglobin levels that are greater than 30% or in which there are symptoms despite oxygen therapy
• is used as an indicator

Answer 7

Methylene Blue

C16H18ClN3S

Question 8

is the substance that gives (donates) electrons

Answer 8

reductant

Question 9

is the substance that gains (accepts) electrons

Answer 9

oxidizer

Question 10

In 1884 the French chemist and engineer proposed one of the central concepts of chemical equilibria

Answer 10

Henry-Louis Le Chatelier

Question 11

A change in one of the variables that describe a system at equilibrium produces a shift in the position of the equilibrium that counteracts the effect of this change.

Answer 11

Le Chatelier’s principle
