ZnSO4 is an amphoteric salt, thus both weakly acidic and weakly basic.
However the solution of Zn2+ and SO42- ions is slightly more acidic (pKa(Zn2+) = 9.66) than basic (pKb(SO42-) = 12.08).
An alkali is a soluble base, and zinc hydroxide is insoluble, so it is a base.
Anything with 'hydroxide' on the end of it is an alkali.
Calcium hydroxide is considered a strong base.
Copper hydroxide is not considered a strong base. It is classified as a weak base.
Rubidium hydroxide is considered a strong base because it dissociates completely in water to form hydroxide ions. This results in a high concentration of hydroxide ions in solution, making it a strong base.
Zinc hydroxide. It is base
An alkali is a soluble base, and zinc hydroxide is insoluble, so it is a base.
Anything with 'hydroxide' on the end of it is an alkali.
Calcium hydroxide is considered a strong base.
Copper hydroxide is not considered a strong base. It is classified as a weak base.
This base is zinc hydroxide.
Rubidium hydroxide is considered a strong base because it dissociates completely in water to form hydroxide ions. This results in a high concentration of hydroxide ions in solution, making it a strong base.
Sodium hydroxide is a strong base.
Barium hydroxide, Ba(OH)2 is a strong base.
Ammonium hydroxide is considered a weak base. It partially ionizes in water to form ammonium ion (NH4+) and hydroxide ion (OH-).
No, zinc hydroxide is not soluble in ammonium hydroxide. Zinc hydroxide is a sparingly soluble compound, meaning it will only dissolve to a very small extent in water. Ammonium hydroxide is not a strong enough solvent to significantly increase the solubility of zinc hydroxide.
Strontium hydroxide is a base, not a salt. It is a chemical compound composed of strontium, hydrogen, and oxygen, and it dissociates in water to release hydroxide ions, making it a strong base.
