Sodium hydroxide in contact with some metals (aluminum, magnesium, and zinc) reacts to produce flammable and potentially explosive hydrogen gas.
Aluminium is actually a very reactive metal that is unusual as it has layer of oxide (Al2O3) on the surface. This oxide is soluble in base forming an aluminate exposing the aluminum surface which then reacts.
Sodium hydroxide solution is highly corrosive and can react with aluminum to produce hydrogen gas and aluminum oxide. This can lead to the formation of pressure inside the container, potentially causing it to rupture or leak. It is better to store sodium hydroxide solution in containers made of materials like polyethylene or glass that are resistant to its corrosive nature.

Why can't we store sodium hydroxide solution in aluminium containers?
Sodium hydroxide reacts with aluminum to form hydrogen gas and aluminum hydroxide, which can lead to the container corroding or even bursting due to the pressure build-up from the gas. This can be a safety hazard and cause damage to the container.
Why sodium Hydroxide Solution Cannot Be Kept In Aluminium Containers?
Sodium Hydroxide in contact with some metals ( Aluminium , Magnesium , Zinc ) reacts to produce flammable and potentially explosive Hydrgen Gas. Aluminium is actually a very reactive metal that is unusual as it has layer of oxide ( Al2O3 ) on the surface. This oxide is soluble in base forming an aluminate exposing the Aluminium surface which reacts.
What are the products of aluminum oxide and sodium hydroxide?
When aluminum oxide reacts with sodium hydroxide, the products formed are sodium aluminate and water. The balanced chemical equation for the reaction is Al2O3 + 2NaOH -> 2NaAlO2 + H2O.
What is the reaction of sodium aluminate in water?
When sodium aluminate is added to water, it dissociates into sodium ions and aluminate ions. The aluminate ions then react with water molecules to form aluminum hydroxide and hydroxide ions. This reaction results in the formation of a colloidal suspension of aluminum hydroxide particles in the solution.
A solution of sodium hydroxide in water is most likely to have a pH close to?
A solution of sodium hydroxide in water will have a pH close to 14, as sodium hydroxide is a strong base that dissociates completely in water to produce hydroxide ions, increasing the pH.
Why can't we store sodium hydroxide solution in aluminium containers?
Sodium hydroxide reacts with aluminum to form hydrogen gas and aluminum hydroxide, which can lead to the container corroding or even bursting due to the pressure build-up from the gas. This can be a safety hazard and cause damage to the container.

Is sodium hydroxide unknown solution?
Sodium hydroxide is not an unknown solution.
Will Sodium hydroxide react with copper?
Yes, sodium hydroxide can react with copper to form copper(II) hydroxide. When sodium hydroxide is added to a solution containing copper ions, a blue precipitate of copper(II) hydroxide is formed.
HOW TO Prepare alum from scrap aluminum?
To prepare alum from scrap aluminum, begin by cutting the aluminum into small pieces and dissolving it in a sodium hydroxide solution. Filter out any impurities, then add sulfuric acid to the solution to precipitate aluminum hydroxide. Lastly, treat the aluminum hydroxide with sulfuric acid and allow the solution to evaporate to obtain alum crystals.
What is the color of sodium hydroxide solution?
Sodium hydroxide solution is colorless.
Is sodium hydroxide solution neutral?
No, sodium hydroxide solution is not neutral. It is a strong base with a pH greater than 7.
What is the molarity of a 3 sodium hydroxide solution?
A 3 M sodium hydroxide solution means there are 3 moles of sodium hydroxide dissolved in 1 liter of solution.
How many pounds of Sodium Hydroxide does it take to make 10 gallons of 50 percent Sodium Hydroxide solution?
To make 10 gallons of a 50% sodium hydroxide solution, you would need 10 pounds of sodium hydroxide. This is because the percentage indicates the weight of sodium hydroxide in the solution. Hence, in a 50% solution, half of the weight of the solution is sodium hydroxide.
What reaction occurs when solutions of aluminum chloride and sodium hydroxide are mixed?
When solutions of aluminum chloride and sodium hydroxide are mixed, a white precipitate of aluminum hydroxide is formed, along with the production of sodium chloride. This is a double displacement reaction where the aluminum ions in aluminum chloride switch places with the sodium ions in sodium hydroxide.
How do you generate sodium hydroxide from sodium chloride?
Sodium hydroxide is prepared from sodium chloride by the electrolysis of the solution.
What gas is formed in the reaction of aluminum metal with aqueous sodium hydroxide?
Hydrogen gas is formed when aluminum metal reacts with aqueous sodium hydroxide. The reaction produces aluminum hydroxide and hydrogen gas.
