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 pH number of sodium hydroxide?
Sodium hydroxide does not have a pH number. The pH of a solution of sodium hydroxide depends entirely on the concentration of it in that solution. To learn how to determine the pH of a sodium hydroxide solution, see the Related Questions links.
Can you make potassium hydroxide by mixing potassium sulfate and calcium hydroxide?
No, potassium hydroxide cannot be made by mixing potassium sulfate and calcium hydroxide. Potassium hydroxide is typically produced through the electrolysis of potassium chloride. Mixing potassium sulfate and calcium hydroxide would not result in the formation of potassium hydroxide.
Is hydroxide a liquid?
The term hydroxide is generally used to refer to an ion and not a "substance" per se. In that light, hydroxide cannot be a solid, liquid or gas as we think of atoms or molecules. The hydroxide ion is a bonded pair of atoms, one of oxygen and one of hydrogen. It has the chemical symbol OH- because this ion "came from somewhere" with a "partner" ion that a "+" charge on it. The ions, because they are in a situation where they've become separated from each other, are not generally considered using the term "liquid" when we look at them (even though they may be in liquid solution).
When sodium hydroxide is added to water what happens?
When sodium hydroxide (NaOH) is added to water, it dissociates into sodium ions (Na+) and hydroxide ions (OH-). This process is exothermic, meaning it releases heat. The hydroxide ions increase the pH of the solution, making it basic. This reaction is highly exothermic and caution should be taken to avoid splashes or burns.
Why is magnesium hydroxide a better antacid than sodium hydroxide?
Sodium hydroxide is a strong base (fully dissolves in water) and is highly caustic. If it touches the skin it can cause severe chemical burns. Swallowing it can result in severe damage, often permanent, to the digestive tract and death. Magnesium hydroxide is a weak base (minimally dissolves in water). It cannot cause the damage that sodium hydroxide does.
Is solution of sodium hydroxide an element?
No. By definition a "solution" has a minimum of two components. An element is a single atomic entity. A solution cannot be an element.
Does amminium hydroxide exists?
Ammonium hydroxide does not exist as a pure compound but rather as a solution of ammonia (NH3) in water. The term ammonium hydroxide is often used as a common name for this aqueous solution of ammonia.
Why ammonium hydroxide cannot be primary standard?
Because it is a instable solution of gaseous ammonia (NH3) in water. (cit.) Ammonium hydroxide (NH4OH) is a common, though not entirely correct name for a solution of ammonia dissolved in water. When dissolved in water ammonia reacts to a small degree with water to produce ammonium hydroxide solution (NH3 + H2O --> NH4+ + OH-). But this only forms in a small amount ammonium (NH4+) and most of the ammonia remains unreacted as NH3. 'Ammonium hydroxide' substance cannot be isolated at all, as any attempt to separate it out will result in it reverting back to ammonia and water. (from wiki-answers)
A volume of 40.0g of aqueous potassium hydroxide was titrated against a standard solution of sulfuric acid. What was the molarity of the solution if 25.7g of 1.50M was needed?
The molarity of the potassium hydroxide solution is 3.30M. This can be calculated by determining the number of moles of sulfuric acid used (0.0171 mol), then equating this to twice the number of moles of potassium hydroxide used (0.00855 mol), and finally dividing this by the volume of the potassium hydroxide solution (0.00258 L).
Can you store lemon pickle in an aluminium utensil Explain?
no, we cannot store lemon pickle in aluminium containers because lemon pickles are acidic in nature and therefore if it is stored in an aluminium container it will damage the surface of the containers thus it not advised to lemon pickle aluminium containers.
Can sodium hydroxide produce pH of 4?
No, sodium hydroxide is a strong base so its pH must be higher than 7.
What is the pH number of sodium hydroxide?
Sodium hydroxide does not have a pH number. The pH of a solution of sodium hydroxide depends entirely on the concentration of it in that solution. To learn how to determine the pH of a sodium hydroxide solution, see the Related Questions links.
How is aluminum mined?
In Runescape you cannot mine Aluminium Ore.
Why cant the pH of aluminium oxide be measured?
Aluminum oxide is insoluble in water, so it does not produce an aqueous solution for pH measurement. Since pH is a measure of the concentration of hydrogen ions in a solution, it cannot be directly measured in the case of aluminum oxide.
An aqueous solution of sodium hydroxide contained in a bottle is labelled 2M. Determine the mass of sodium hydroxide used in preparing?
To determine the mass of sodium hydroxide used in preparing a 2M solution, you need to know the volume of the solution you are preparing. The concentration of 2M means there are 2 moles of sodium hydroxide in 1 liter of solution. You can use the formula: mass = molarity x volume x molar mass to calculate the mass of sodium hydroxide. For example, if you are preparing 1 liter of the solution, the mass would be 2 x 1 x 40 g/mol (molar mass of NaOH) = 80 grams.

Can food be reheated in aluminium foil containers?
Yes, food can be reheated in aluminum foil containers. However, it's important to ensure that the food is heated evenly, not left too long in the foil as it may cause the foil to melt or react with certain acidic foods. It's also recommended to avoid using aluminum foil in microwave cooking.
