The balanced chemical equation for the reaction of 2 CrO 4 2 − with SO 3 2 − in a basic solution is to be written, the number of grams of chromium that are present in the alloy sample is to be determined, and the percentage by mass of chromium in the alloy is 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 equivalent to the total mass of the products.

In general, which is more polar, the stationary phase or the mobile phase?
The stationary phase is always more polar
The mobile phase is always more polar
It depends on our choices for both stationary and mobile phase
Their polarity doesn't really matter so we never consider it
