Titanium oxide is amphoteric, meaning it can act as either an acid or a base depending on the reaction conditions. In acidic conditions, titanium oxide can behave as a base by accepting protons, while in basic conditions, it can act as an acid by donating protons.
- This is not an oxide, is a sulfide.- The term pH is applied to liquids.
The oxide formed in gold is neither an acid nor a base. Gold oxide (Au2O3) is considered to be amphoteric, which means it can exhibit characteristics of both an acid and a base depending on the reaction it undergoes. It can react with both acids and bases to form different compounds.
When a metal oxide neutralizes an acid, it produces a salt and water. This reaction is a type of acid-base reaction where the metal oxide acts as a base and the acid acts as an acid. The salt formed usually contains the metal cation from the metal oxide and the anion from the acid.
Gold does not react directly with oxygen, however if you succeed in getting gold oxide indirectly, it decomposes at 205C. The oxide is neither acid nor base however gold ions are acidic (like protons are acidic)
Fe2O3 It is neither an acid or a base, and it is a compound, not an element
Al2O3 is an oxide. It is the chemical formula for aluminum oxide, which is a compound formed by the bonding of aluminum and oxygen atoms. Oxides typically have basic properties.
Gallium hydroxide is a base. It is formed when gallium oxide reacts with water to produce hydroxide ions.
Its a metal oxide so it'll be a base. Acids are mainly made with a non-metal oxide, though some metal (amphoteric) oxidesare also (mainly weak) acid forming oxides
Nickel (II) chloride is neither a base nor an acid; it is a salt composed of a metal cation (nickel) and a chlorine anion. It is formed by the reaction of nickel oxide with hydrochloric acid.
