Sodium Na Magnesium Mg Aluminium Al Zinc Zn Iron Fe Nickel Ni Tin Sn Lead Pb Hydrogen H Copper Cu Less reactive Mercury Hg than hydrogen Silver Ag Platinum Pt Gold Au Gold and platinum are noble metals i.e.,non reactive towards acid, base & other substance. Displacement reaction displacement. Non metal displacement. Metal displacement *More reactive metal displaces a lesser reactive metal from its solution. e.g. Fe + CuSO4-------->FeSO4 + Cu Cu + FeSO4------------>No Reaction Because Cu is less reactive than Fe. Non displacement *Metal reacts with acid & liberates hydrogen gas. e.g. Mg + 2HCl--------->MgCl2 + H2 Double displacement *Reaction in which two ionic compounds in the reaction solution phase react by exchange of their ions. e.g. BaCl2 + Na2SO4--------->BaSO4 + 2NaCl (white p.p.t) Precipitation reaction *Two compounds on mixing react to form an insoluble compound (ppt). e.g. Ca(OH)2 + CO2-------->CaCO3 (milky suspension) Double displacement reaction is also considered as a precipitation reaction. Neutralisation reaction *Acid reacts with base to form salt and e.g.
