In a double replacement reaction the cations and anions switch to make two new compounds. It has the general form of AB + CD ==> AD + CB. An actual example might be:AgNO3(aq) + NaCl(aq) ==> AgCl(s) + NaNO3(aq). In a double replacement, one of the products must be either a precipitate (solid), a weak electrolyte, water, or a gas, otherwise, if all products are soluble, then there is no reaction.
The mass remains constant during the reaction. HCl + Mg → MgCl + H2
