- This is not an oxide, is a sulfide.
- The term pH is applied to liquids.
acid.
Silver sulfide is composed of silver, a metal, and sulfur, a non-metal; therefore, it is an ionic compound and a salt.
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.
Silver oxide is a basic compound because it contains the oxide ion (O2-), which can accept protons and therefore acts as a base by reacting with acids to form water and a salt.
Silver carbonate is a CHEMICAL SALT. Hence it is neither an acid nor a base.
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.
Does it contain H+ ions? No, so it is not an acid.Does it contain OH- ions? No, so it is not a base/alkali.Silver nitrate is a salt formed by reacting silver with nitric acid.
Gallium hydroxide is a base. It is formed when gallium oxide reacts with water to produce hydroxide ions.
