Document Summary

Solvation: helps stabilize the ions and solution and prevents cations and anions from recombining; ion and water shell are free to move about. Strong electrolytes: exist in solution completely as ions. Weak electrolytes: exist in solution mostly in form of neutral molecules. Chemical equilibrium: relative numbers of each type of ion/molecule are constant over time; reaction equation arrows go both ways. Precipitate: insoluble solid formed by a reaction in solution; occur in precipitation reactions. Solubility: amount of substance that can be dissolved in a given quantity of solvent at a given temperature. Exchange reactions (metathesis): cations and anions appear to exchange partners. Molecular equation: shows complete chemical formula of reactants and products; shows chemical formulas without ionic character: Complete ionic equation: all soluble strong electrolytes shown as ions. Spectator ions: play no role in reaction; cancelled out (not written) in net ionic equation.

Fill the questions according to Data Table 7-2

5. balanced formula equation: for each combination of solutions that produced new product. write correct chemical formulas for the new compounds that could form from the ions present. Indicate which of the new compunds is a precipitate. If no reaction occurs, write NR.

6. complete ionic equation: write complete ionic equations for the precipitation reactions that you observed. show the reactants as ions, the precipitate as a solid, and the spectator ions as unchanged. balance each equation for mass and change. the total charge should be zero on each side of the equation.

7. net ionic equation: write the net ionic equations for each reaction in the preceding question.
