![]() ![]() Single displacement (AB + C -> AC + B): Magnesium metal reacts with copper (II) chloride to form copper metal and a colorless solution. Mg ^2+ (aq) + 2 NO 3 ^1- (aq) + 2Li ^1+ (aq) + CO 3 ^2- (aq) -> Mg CO 3(s) + 2Li ^1+ (aq) + 2NO 3 ^1- (aq)ģ.Write the Net Ionic Equation: From the IE, eliminate the corresponding ions for the reactants and the products so that the only product left is the precipitate and the only reactants left are the ions that make up that precipitate. The precipitate is left in its molecular formula. In an IE, all the soluble compounds are written as their constituent ions. Write the Ionic Equation: Ionic compounds (I), strong acids (SA), and strong bases (SB) all split up 100% into ions when dissolved in water. Balance the chemical equation, indicating the states of matter with subscripts (refer to solubility rules or a chart). There are 3 steps to writing a NIE: ( *charge = ^ -> ex: H ^1+ )ġ. Precipitate reactions can be represented in 3 different ways we will be writing them as Net Ionic Equations. In a NIE, only ions that react to form the solid, and the produced precipitate, are displayed in the final written equation. If none of the ions mentioned above is present in the chemical equation, you will most likely be given a Solubility Chart. For this course, you are only responsible for memorizing the rules mentioned above. *** Be aware that there are other solubility rules and that there are exceptions to the rules. Students will analyze the chemical equation for the reaction and see that all atoms in the reactants end up in the products. Summary Students will combine two clear colorless solutions (baking soda solution and calcium chloride solution) and see the formation of a solid and a gas. All NO3- (nitrate) ions form soluble compounds A solid formed from two solutions is called a precipitate. All NH4+ (ammonium) ions form soluble compounds All group 1A (alkali metals) ions form soluble compounds ` However, it would also be beneficial for you to familiarize yourself with the following General Rules of Solubility: To determine whether a product is insoluble, we can refer to a Solubility Chart. When writing a precipitate reaction, it is important to indicate the states of matter using subscripts: Typically, the types of chemical reactions that we will be dealing with will be double displacement reactions, but there are also single displacement and synthesis reactions that demonstrate precipitate reactions. ![]() A precipitate is an insoluble compound produced by the synthesis of two soluble compounds, also known as aqueous solutions. When a chemical reaction results in the formation of a solid, we call this a precipitate reaction. ![]()
