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 is the balance equation for chemical reaction of aluminium with sodium hydroxide?
2 Al + 6 H2O > 2 Al(OH)3 + 3 H2 Al(OH)3 + NaOH > Na+ + [Al(OH)4]- __________________________________________________________________ 6H2O(l)+2Al(s)+2NaOH(aq)--------------- 2NaAl(OH)4(aq)+3H2(g)
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 Sodium hydroxide solution can not be stored in aluminum containers?
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.
Is sucrose soluble in sodium hydroxide?
No, sucrose is not soluble in sodium hydroxide without water.

Which gas is liberated when an alkaline solution of sodium nitrate is warmed with aluminium?
Aluminium react with sodium hydroxide releasing hydrogen.Sodium nitrate is decomposed by heating releasing nitrogen dioxide.
Is sodium hydroxide unknown solution?
Sodium hydroxide is not an unknown solution.
Describe the test for aluminium ions?
Test: Add aqueus sodium carbonate solution, then warm it. Observation: Formation of white precipitate. Deduction: The presence of aluminum ions, Al3+ Or Test: Observation: Add aqueous sodium hydroxide White precipitate occur Add aqueous sodium hydroxide (excess) & warm White precipitate solute Test with red litmus paper Changes red - blue Deduction: The presence of aluminum ions, Al3+
How could you separate magnesium hydroxide Mg(OH)2 from alminium hydroxide Al(OH)3?
Add sodium hydroxide solution; aluminium hydroxide will dissolve but Mg(OH)2 remain.
What is the color of sodium hydroxide solution?
none, it is clear
Is sodium hydroxide solution neutral?
No. A sodium hydroxide solution is very basic.
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.
How do you generate sodium hydroxide from sodium chloride?
Sodium hydroxide is prepared from sodium chloride by the electrolysis of the solution.
What has the highest pH value dilute sodium bicarbonate or lemon juice or dilute sodium hydroxide solution?
dilute sodium hydroxide solution
What is chemical formula for aqueous solution of sodium hydroxide?
The chemical formula for the aqueous solution of sodium hydroxide is NaOH (sodium hydroxide) dissolved in water.
