Alkali, such as sodium hydroxide or potassium hydroxide, reacts with aluminum to produce hydrogen gas and soluble aluminum hydroxides. This reaction occurs because alkali can break down the protective oxide layer on aluminum, allowing further reaction with the metal. The reaction is exothermic and can be vigorous, leading to the release of flammable hydrogen gas. As a result, aluminum is generally not stable in strongly alkaline environments.
What else can I help you with?
Is sodium a alkali earth metals?
Sodium nitrate is not alkali. It is a neutral compound.
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
Does alkali has a pH of over 12?
Some do. But all alkali have a pH value of more than 7.
How do you know if something is an alkali just by the name?
You can identify an alkali by its name if it contains specific terms or elements associated with alkalis. Typically, alkalis are hydroxides of alkali metals (like sodium or potassium) or alkaline earth metals (like calcium). If the name includes "hydroxide," such as sodium hydroxide (NaOH) or potassium hydroxide (KOH), it indicates an alkali. Additionally, the presence of alkali metal names in the formula or common names suggests it is an alkali, such as sodium or potassium compounds.

What is the difference between sodium and aluminum'?
Sodium is a highly reactive alkali metal whereas aluminium is a less reactive metal in the boron group.
Why alkali metals used in photoelectric effect?
Alkali metals are used in the photoelectric effect because they have low ionization energies, making it easier for photons to eject electrons from their surface. This makes them efficient materials for producing a photoelectric effect. Additionally, alkali metals have a clean surface that allows for reliable and consistent results in experiments.

Is aluminum an alkali metal?
No, aluminum is not an alkali metal. Alkali metals are the group of elements in the periodic table that include lithium, sodium, potassium, rubidium, cesium, and francium. Aluminum belongs to a different group of elements called the post-transition metals.
What salt is formed when aluminium reacts with potassium hydroxide during preparation of hydrogen from alkali's?
Potassium aluminate is the salt formed when aluminum reacts with potassium hydroxide in the preparation of hydrogen from alkalis. This reaction produces hydrogen gas along with the formation of potassium aluminate as a byproduct.
