It could have been either because the two solutions did not react at all, or because both the products and reactants of the resulting chemical equation are soluble. As you will see from this lab exercise, agglutination is more sensitive than precipitation reaction because it takes a lot of more soluble antigens and antibody molecules to form a visible precipitation. In this interactive and animated object, learners use solubility rules to predict when an insoluble ionic compound will precipitate in a double replacement reaction. 4.
