Acidic oxides are the oxides to which acids correspond. Those. The oxidation state of a non-metal in an oxide corresponds to the oxidation state of the same non-metal in an acid.
a) When sulfur burns, a mixture of acids is formed.
О2 + S = SO2 – Acidic oxide. Corresponds to sulphurous acid (H2SO3).
O2 + S = SO3 – Acidic oxide. Corresponds to sulfuric acid (H2SO4).
b) Depending on the temperature, carbon burns with the formation of various oxides.
О2 + С = СО – Non-salt-forming oxide.
О2 + С = СО2 – Acidic oxide. Corresponds to carbonic acid (Н2СО3).
c) 3О2 + 6Al = 2Al2O3 – Amphoteric oxide.
d) O2 + P = P2O5 – Acidic oxide. Corresponds to phosphoric acid (Н3РО4).
О2 + Р = Р2О3 – Non-salt-forming oxide.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
