Chemical Reactions Synopsis

Chemical Reactions

Purpose:

In living organisms and in our environment many extremely crucial aqueous reactions occur. In these reactions water acts as the solvent and the dissolved molecules or ions are the solutes. These make up the reactants involved in the reaction. One of the most important elements of chemistry is writing the equations for these reactions, this laboratory will not only help us to learn and improve upon writing chemical equations but it will also allow us to observe chemical reactions as they occur.

Procedure:

I. Double Replacement (Metathesis) Reactions
A. Reactions between solutions of electrolytes producing precipitates
B. Example: NaCl(aq)+AgNO3(aq)„³AgCl(s)+NaNO3(aq)
1. 3 strong electrolytes (aq) and 1 solid (AgCl, solid)
C. NaCl(aq)+KNO3(aq)„³NR (no reaction, no precipitate formed)
D. Net Ionic Equation
1. Is written after you eliminate the ¡§spectator ions¡¨ in the molecular equation, these are ...
