Which of the following pairs will give displacement reaction:- Sodium chloride solution and copper metalMagnesium chloride solution and Aluminium metalFerrous sulphate solution and silver metalSilver nitrate solution and copper metal |
| Answer» ACCORDING to the reactivity SERIES of METALS, COPPER metal is less reactive than SODIUM metal. Hence, no displacement reaction will occur between NaCl solution and copper metal. Again, aluminium metal is less reactive than Mg, so no displacement reaction will occur between MgCl₂ solution and aluminium metal. | |
