Copper is below hydrogen in the electrochemical series and thus does not react with acids to liberate hydrogen, unless they are also strong oxidising agents. what is the correct meaning of evaporation. Copper metal react with hot and concentrated sulphuric acid but no hydrogen gas is produced. Metals to the left of hydrogen in the series lose electrons when they ionize, whereas those to the right, which do not react with hydrochloric acid, gain electrons when they ionize. Magnesium hydroxide and oxide are both basic and will therefore react with dilute sulphuric acid to form magnesium sulphate.
