Sulphate chemistry
WebThe electrolysis of copper sulfate solution (CuSO 4 (aq)) Copper sulfate solution is composed of copper ions (Cu 2+), sulfate ions (SO 4 2-), hydrogen ions (H +) and hydroxide ions (OH –). At the cathode a brown layer is formed. This is copper. Explanation: copper ions gain electrons (reduction) and form atoms of copper. Web19 Jul 2024 · Both anions show resonance in their chemical structures; The oxidation state of oxygen in both anions is -2. The sulfur in both species can undergo reduction reactions. Difference Between Sulfate and Sulfite Definition. Sulfate: Sulfate is an anion composed of a sulfur atom bonded to four oxygen atoms around it.
