alkali metal + oxygen --> metal oxide
metal oxide + water--> metal hydroxide
metal hydroxides are strong alkalis, corrosive pH=14

Alkali metals form hydroxides when they react with oxygen, which are strong bases. These solutions have a high pH, typically around 13-14 on the pH scale.

The alkali metals react with oxygen and form compounds that dissolve in water to produce solutions that are what on the pH scale?
its not D. none of the above
What do alkali metals behave like?
Alkali metals are highly reactive and tend to form ionic compounds by easily losing their outermost electron. They are soft, shiny, and have low melting points. In reactions, alkali metals typically produce hydrogen gas and form basic solutions.
What alkali metals are insoluble?
Alkali metals like lithium, sodium, and potassium are generally soluble in water due to their high reactivity and tendency to form ionic compounds. Alkali metals are not typically considered insoluble in water.
Why the group 1 element of periodic table are called alkali metals?
Group 1A elements are active metals. They are so active that they are never found free in nature. They are usually stored in oil. They form compounds with oxygen that dissolve in water to give solutions that are alkaline or caustic. They are called alkali metals, or simply the alkalis.
What is the difference between a base and an alkali?
Alkali is a basic, ionic salt of an alkali metal or alkaline earth metal element. Alkalis are best known for being bases that dissolve in water. (Most common form is hydroxide.)A base is most commonly thought of as an aqueous substance that can accept H+ ions.A soluble base is also often referred to as an alkali if hydroxide ions (OH−) are involved."All alkali are bases but not all bases are alkali"

its not D. none of the above
Is Carbon an alkali?
No, carbon is not an alkali. It is a non-metal element that is commonly found in organic compounds and all living organisms. Alkalis are a subset of bases that dissolve in water to produce hydroxide ions.
Does alkali dissolve in water?
Alkalis (bases) typically dissolve in water to form alkaline solutions. This process involves the alkali ions dissociating in water to produce hydroxide ions, which increase the pH of the solution. Examples of alkalis that dissolve in water include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
Is alkali soluble in water?
Yes, alkali compounds are generally soluble in water. Alkalis are bases that, when dissolved in water, produce hydroxide ions, which make them generally soluble in aqueous solutions.
What do alkali metals behave like?
Alkali metals are highly reactive and tend to form ionic compounds by easily losing their outermost electron. They are soft, shiny, and have low melting points. In reactions, alkali metals typically produce hydrogen gas and form basic solutions.
What is alkali in?
Alkali refers to a group of basic compounds that dissolve in water to form hydroxide ions. These compounds are the opposite of acids on the pH scale. Examples of alkalis include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
Is lithium hydroxide a acid or a alkali?
Lithium hydroxide is considered a strong alkali because it readily dissociates in water to produce hydroxide ions, which makes the solution basic. It does not act as an acid in aqueous solutions.
Compounds that release ions when they dissolve in water are called?
Substances that form ions when dissolved in water are electrolytes.
What alkali metals are insoluble?
Alkali metals like lithium, sodium, and potassium are generally soluble in water due to their high reactivity and tendency to form ionic compounds. Alkali metals are not typically considered insoluble in water.
Is kitchen cleaner a weak alkali?
Kitchen cleaner is commonly a weak alkaline solution, as it often contains ingredients like ammonia or sodium hydroxide to help break down grease and grime. Alkaline solutions can help to dissolve fats and oils more effectively than acidic solutions.
What name is given to basic oxides which can dissolve in water?
Basic oxides that can dissolve in water are known as metal hydroxides. When they dissolve in water, they form alkaline solutions due to the presence of hydroxide ions (OH-) in the solution.
What does alkali stand for in science?
In science, alkali refers to a basic (pH greater than 7) substance that dissolves in water to produce hydroxide ions (OH-). Alkalis are also known as bases and are the opposite of acids in terms of their chemical properties.
