Document Summary
Describing reactions in solution formula equation (molecular equation) Gives the overall reaction stoichiometry but not necessarily the actual forms of the reactants and products in solution. Reactants and products generally shown as compounds. Use solubility rules to determine which compounds are aqueous and which compounds are solids. Represents as ions all reactants and products that are strong electrolytes. Includes only those solution components undergoing a change. Spectator ions are not included (ions that do not participate directly in the reaction). Solving stoichiometry problems for reactions in solution. Identify those present in the combined solution & determine what reaction if any occurs. Write the balanced net ionic equation for the reaction. Calculate the moles of product(s), as required. Convert to grams or other units, as required. For a strong acid and base reaction: h+(aq) + oh (aq) h2o(i) List the species present in the combined solution before any reaction occurs, and decide what reaction will occur.
