Some examples of the homogeneous mixtures are known as sugar, salt, water, dye, air, and blood A heterogeneous mixture has a clear identifying property where one can see various different components of the mixture It is a reaction system where the products and the reactants are found in two or more phases• Apple juice is homogeneous • Orange juice with pulp is heterogeneous • Chocolate dough is homogeneous • Italian salad dressing is heterogeneous In heterogeneous catalysis, the reaction starts at the surface of the solid catalyst and so it is also known as surface catalysis Example Manufacture of H 2 SO 4 by contact process involves oxidation of SO 2 into SO 3 in presence of V 2 O 5 (solid) as catalyst
