Precipitation Reactions. Here AB and CD are usually aqueous ionic compounds (or acids) consisting of aqueous ions (A+ and B-, C+ and D-). When a double replacement reaction occurs, the cations and anions switch partners, resulting in the formation of two new ionic compounds AD and CB, one of which is in the solid state.
H: + 1 + 1. C l: − 1 − 1. Since there is no overall transfer of electrons, this can't be a redox reaction, and that means activities won't matter here. That means there must be another driving force for this reaction - another reaction pattern that fits better.

It is balanced, as there are equal amounts of each element on each side. NaOH (sodium hydroxide) and HCl (hydrochloric acid) are the reagents.
The first reaction is the acid-base reaction. When vinegar and baking soda are first mixed together, hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda. The result of this initial reaction is two new chemicals: carbonic acid and sodium acetate. The second reaction is a decomposition reaction.

8 Some students investigated displacement reactions involving three different metals and solutions of their salts. This equation represents one of these reactions: zn(s) + CuS04(aq) ZnS04(aq) + cu(s) This reaction occurs because zinc is more reactive than copper. When a displacement reaction occurs, there is a temperature rise. The bigger the

Purpose: Double-displacement reactions involve the switching of cations between two compounds.The prediction and balancing of these reactions isn't too much of a challenge for students at this stage, however, they now must consider whether or not each product will remain as part of the aqueous solution or will form a precipitate.
Both of these reactions generate gases as products—CO 2 and H 2 S, respectively. But H 2 S­ is fairly soluble in water, so it doesn’t bubble out of solution as rapidly as CO 2 does. Two more tubes done! 4. Identify MgCl 2 and BaCl 2 (and HCl and H 2 SO 4).
