The hydroxide anions in calcium hydroxide have covalent bonding between oxygen and hydrogen atoms, and these anions are ionically bonded to calcium cations to form the complete compound.


What is true about a hydroxide ions?

Hydroxide ions are anions with the chemical formula (OH)-.


How is it possible for calcium hydroxide to have both covalent and ionic bonding?

Calcium hydroxide has ionic bonding between calcium and hydroxide ions, as calcium donates electrons to hydroxide to form ionic bonds. The hydroxide molecule itself, however, has covalent bonding between the oxygen and hydrogen atoms within the molecule.

What is metal hydroxide?

Metal hydroxide is a type of chemical compound formed by a metal cation combined with one or more hydroxide anions. Examples include sodium hydroxide (NaOH) and iron(III) hydroxide (Fe(OH)3) which are commonly used in various industrial processes. Metal hydroxides are often used as bases in reactions and are characterized by their alkaline properties.


What is Iron hydroxide made of?

Iron hydroxide is a chemical compound made of iron (Fe) and hydroxide (OH) ions. It is commonly formed when iron reacts with water or hydroxide-containing compounds.


What do you observe when ammonium hydroxide is added o iron (iii) choloride?

When ammonium hydroxide is added to iron (III) chloride, a brown precipitate of iron (III) hydroxide is formed. This brown color is characteristic of iron (III) hydroxide.


How do you make iron sulfate hydroxide and oxide?

To make iron sulfate, mix iron oxide with sulfuric acid. For iron hydroxide, mix iron sulfate with a strong base like sodium hydroxide to precipitate out the iron hydroxide. Iron oxide can be made by heating iron metal in the presence of oxygen.
