Redox reactions group 7
WebReaction with oxides and hydroxides. Group 2 oxides and hydroxides, formed with the reaction with oxygen and water are bases. These can neutralise acids to form a salt and water. For example: $$ MgO_{(s)} + 2HCl_{(aq)} \rightarrow MgCl_{2(s)} + H_{2}O_{(l)} $$ This is not a redox reaction however as the oxidation numbers remain unchanged ... Web20. júl 2024 · The only atoms which change are Mn, from +7 to +2, a reduction, and S, from +4 to +6, an oxidation. The reaction is a redox process. SO 2 has been oxidized by MnO 4–, and so MnO 4– is the oxidizing agent. MnO 4– has been reduced by SO 2, and so SO 2 is the reducing agent. b) The oxidation numbers show that no redox has occurred.
