In chemistry, an amphoteric compound is a molecule or ion that can react both as an acid as well as a base. Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide. Al2O3 is an example of an amphoteric oxide.
pH is a measure of how acidic or basic a chemical is when it's in aqueous (water) solution.A neutral pH value (neither an acid nor a base) is 7. Substances with a pH greater than 7 up to 14 are considered bases. Chemicals with a pH lower than 7 down to 0 are considered acids.The closer the pH is to 0 or 14, the greater its acidity or basicity, respectively.
Classify common substances as acidic, basic or neutral Chemical substances can be classified as acidic, basic or neutral. Classification is usually based on the concentration of hydrogen ions (H + ), or hydronium i ons ( H 3 O + ), produced when a substance is dissolved in water.
Pure water has a neutral pH of 7. pH values lower than 7 are acidic, and pH values higher than 7 are alkaline (basic). Table 1 has examples of substances with different pH values (Decelles, 2002; Environment Canada, 2002; EPA, date unknown).
