Yes, anything with 'hydroxide' on the end of it is an alkali.
Copper(I)- and Copper(II)-hydroxide are both very insoluble hydrates of the corresponding oxides of copper. (Cu2O.H2O = 2CuOH and CuO.H2O = Cu(OH)2 )
Copper oxide is not considered an alkali. Alkalis are bases that dissolve in water to produce hydroxide ions, while copper oxide is a basic oxide that does not dissolve in water to form hydroxide ions.
NO, because copper sulphate doesn't contain hydroxide ions, which is responsible for basic nature.
Alkali. IF something contains hydroxide ions it is an alkali.
Potassium hydroxide is both an alkali and a base. Alkali typically refers to a soluble base, and since potassium hydroxide dissolves in water to form hydroxide ions, it is considered an alkali. Additionally, as a strong base, it can accept protons from acids, making it a base.
A hydroxide solution is typically considered an alkali. This is because hydroxide ions (OH-) present in the solution can accept protons, leading to a basic (alkaline) pH.
Copper oxide is not considered an alkali. Alkalis are bases that dissolve in water to produce hydroxide ions, while copper oxide is a basic oxide that does not dissolve in water to form hydroxide ions.
NO, because copper sulphate doesn't contain hydroxide ions, which is responsible for basic nature.
Copper metal itself does not react with sodium hydroxide. But when NaOH is added to a solution of copper ions, it would form a light blue precipitate, which is copper(II) hydroxide, and will NOT dissolve with the excess alkali.
Alkali. IF something contains hydroxide ions it is an alkali.
An alkali is a base, a hydroxide (containing the group OH-), as sodium hydroxide - NaOH.
No. An alkali is a compound: the hydroxide of al alkali metal.
Potassium hydroxide is both an alkali and a base. Alkali typically refers to a soluble base, and since potassium hydroxide dissolves in water to form hydroxide ions, it is considered an alkali. Additionally, as a strong base, it can accept protons from acids, making it a base.
Lithium hydroxide is the strongest alkali in the alkali metal group.
Metallic copper does not react with sodium hydroxide. But if sodium hydroxide is added into a solution of copper ions, it would form Copper(II) Hydroxide. It is a precipitate which is insoluble in water.
A hydroxide solution is typically considered an alkali. This is because hydroxide ions (OH-) present in the solution can accept protons, leading to a basic (alkaline) pH.
base which is soluble in water is called alkali. example the lithium,calcium sodium ,potassium,rubidium ,francium all are alkali metals. they form sodium hydroxide,potassium hydroxide,calcium hydroxide all are strong bases .when they dissolve in water they form strong alkali.
Yep, everything with 'hydroxide' can be called an alkali no matter its state of matter. :)
