    water, and the precipitate as an insoluble solid. Step3:   The ions that appear in the same form on both sides of the equation are      referred to as  spectator ions , since they do not participate in the reaction.     In this reaction the Na +1  and the NO 3 -1  are the spectator ions.     To more accurately describe this reaction we write a    net ionic equation   .

Ag +1 (aq)   + Cl - 1 (aq)       AgCl  (s)     The net ionic equation includes only those compounds and ions that undergo      a chemical change in aqueous solution and does not include spectator ions.             Note :  If all reactants and products are soluble      there will be  no  precipitate  and therefore  no  reaction Acid/Base Reactions Compounds that dissociate into ions when in aqueous solution are said to ionize. Acids are compounds containing Hydrogen that ionize to give off Hydrogen ions (H + in water.  Bases are compounds that ionize to give off Hydroxide ions (OH - ) in water.   Acids and bases are classified into strong and weak: Strong acids and bases completely ionize in aqueous  solution whereas weak acids and bases only partially ionize in solution. Strong Acids:       HCl H 2 SO 4     HNO 3 Strong Bases:       NaOH      KOH When a strong acid reacts with a strong base the products are always a salt and water. strong acid + strong base    salt + water Ex:  Combine a solution of hydrochloric acid with a solution of sodium hydroxide Step1:  Write the complete    molecular equation   .     HCl  (aq)  + NaOH  (aq)     NaCl + H 2 O Step 2:  Write the    total ionic equation   .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
