The balanced net ionic equation for the reaction of Sn 2 + with Cr 2 O 7 2 − in an acidic solution is to be written, the number of grams of tin in the alloy sample and the percentage by mass of tin in the solder are to be calculated. Concept Introduction: The reactions in which the addition of oxygen atoms or the removal of hydrogen atoms takes place are known as oxidation reactions. The reactions in which the addition of hydrogen atoms or the removal of oxygen atoms takes place are known as reduction reactions. The chemical reactions in which one reactant gets oxidized while the other gets reduced during the reaction are called the oxidation-reduction reactions or the redox reactions. Stoichiometry involves calculations on reactants and products and considers the total mass of the reactants to be equivalent to the total mass of the products.
