Document Summary
4. 2 classifying chemical reactions: precipitation reaction : is one in which dissolved substances react to form one (or more) solid products. A compound is soluble in a particular liquid if it dissolves in that liquid. A compound is insoluble if it does not dissolve in the liquid. An aqueous solution (aq) is a homogeneous mixture of a substance with water. When ionic compounds dissolve in water, they usually dissociate into their component ions. Practice problem: predict the result of mixing reasonably concentrated solutions of the following ionic compounds. If precipitation is expected, write balanced equation for each of the following reaction. 4, slide 13) (a) potassium sulfate and barium nitrate. First, write out the ionic formulas for the compounds given. Next, breakdown the ionic compounds into separate cations, and anions (aq) (aq) You then see what your possible products are, remember, cations can not create products with another cation.
